In this thesis, a series of complexes based on aromatic multicarboxylic acids have been successfully synthesized in solutions or under hydrothermal conditions. Their structure and properties are investigated.(1) Eight complex compounds have been synthesized and characterized by X-ray single crystal diffractive technology: The eight complexes are listed as following: [Cu242] complex 1 [Cd22(H2O)4]·4H2O complex 2 [Co(H2btc)(H2O)3] complex 3 [Co2(H2O)2]·H2O complex 4 [Ni22(H2O)4] complex 5 [Cu22(H2O)4] complex 6 [Co(H2biim)2(H2O)2](H2btc) complex 7 [Zn(H2biim)2(H2O)2](H2btc) complex 8 The structure of complex 1 is dinuclear complex resulted from weak interactions（0-D chain）; complex 2 is 1-D chain stucture result from interactions of water molecules; complex 3、4、5、6 are coordination polymers using hydrothermal synthses, where the first kind ligand is H4btc, the second kind ligand is phen and Co2+、Ni2+、Cu2+ as center ions, respectively. While the coordination enviroment of Co2+ is the same in complex 3, the coordination geometries around the Co atoms in complex 4 are obviously different because of the different reaction conditions. In complex 4, the 1-D chains are connected into 2-D layer through carboxy groups of ligand H4btc. The structures of complex 5、6 are 1-D chain stucture result from interactions of carboxy groups in ligand H4btc. Complex 7、8 are homeomorphy compounds. Either of them are linked to the 3-D chains through intermolecular hydrogen bonds. Each H4btc lose two protons and H2btc2- acts as negative electron balance.

Structures of Na~+-AD ion-complexes with 1 or 2 H2O molecules were obtained. It was found that H2O can bond with Na~+ in the structure of Na~+-AD to form Na-O van der Waals bond. H2O molecule can also bond with N or O atoms in AD moiety to form H-bonds as N-H…Ow or O…Hw-Ow. The former process takes place more easily. The most stable structures of Na~+-AD ion-complexes with 1 and 2 H2O molecules are W-C7AB and 2W-C7AB, respectively.αB conformer of Na~+-AD can not exist in the presence of 2 H2O molecules.

Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55～50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55～44.19% and Mn of HCl-extractable species were 20.66～28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5.

不同的提取剂对水蓼根、茎、叶的提取结果表明，随着锰处理浓度增加，水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化，说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加；在茎中，水提取态锰含量占总锰的34.55-50.26%，且随锰处理的增加其水提取态锰的比例增加，这有利于锰向上运输；水蓼的叶片中，水提取态锰占总锰的38.55-44.19%，盐酸提取态锰占总锰的20.66-28.74%，说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。

It is often said that in Kripkean cases, conceivability does not entail possibility: it is conceivable that water is not H2O (in that it is coherent to suppose that water is not H2O), but it is not possible that water is not H2O.

在Kripke式例子中，常常被认为'可设想'并不导出'可能'：可设想水不是H2O（因为假设水不是H2O，这是融贯的），但水不是H2O是不可能的。

All the compounds are characterized by IR and elemental analysis.we design and prepare a bipyridinium supramolecular compound and six coordination compounds, which are also characterized by IR, elemental analysis and X-ray structure analysis.

Isopiestic measurements have been carried out at 298.15K for the quaternary aqueous solution H2O+KCl+NaCl+NH4Cl saturated with potassium chloride and its ternary sub-systems H2O+KCl+NaCl and H2O+KCl+NH4Cl.

Three important conclusions are as follows:(1) the H2O content in garnet and omphacite can be up to 2000ppm and 3000ppm by weight respectively, indicating that they are significant carrier recycing surficial water into deep earth;(2) the heterogeneous distribution at the small scale of the H2O content and hydrogen isotopic ratios suggest that the whole subduction- exhumation process should be very fast;(3) the regular decrease of H2O content from rim to core within some garnet and omphacite grains indicates that hydrogen diffused out from mineral lattice during exhumation in response to sharp pressure decrease, and such hydrogen is expected to be involved in the early-stage retrograde metamorphism.

取得的主要科学认识包括：(1)石榴石和绿辉石的结构水含量可以分别高至2000ppm和3000ppm，这表明它们是板块俯冲过程中将地表水携带进地球深部的重要载体；(2)水含量和氢同位素组成表现出小尺度的不均一分布，说明板块的俯冲和折返过程是十分快速的；(3)在板块折返的早期，由于压力的降低，矿物中的H 会发生不同程度和尺度的扩散，这是早期退变质流体的重要来源。

They are most abundant in quartz of pegmatitic leucosomes and granitic rocks, and represent the fluid appearing in their cooling stage. The DL(H2O) of such fluid is 0.93～0.96g/cm3 corresponding to P≈0.6GPa which is compatible with condition when the rapid decompression in this region was ended. 3 CO2-H2O two or three phases inclusions. They are the most widespread, and more frequently in clusters and in intragranular tails in quartz. The relative content of CO2+CH4 and H2O is considerably variable. They are also characterized with lower density (0.6～0.8g/cm3) and low pressure about 0.3～0.4GPa, and may be originated by mixture of carbonic liquid from breaking of most inclusions of peak stage and aqueous liquid of magmatic source. After entrapment, the further decrease of temperature to lower than 330℃ made such fluid separated to two or three phases.
