In complex 1,Cucan be described as a four-coordinated square planar geometry.Compound 8 is the sodium salt of plumbagin and exists as ionic compound.Compounds 9-16 are the rare earth complexes of plumbagin with La,Y,Dy,Sm,Gd,Nd,Erand Eu.Compound 17 is binuclear Y complex.18 is mononuclear Ycomplex with plumbagin and another ligand from Plumbago Zeylanica.Compounds 19-21 are the ternary complexes with plumbagin and 2,2\'-bpy and phen as assistant ligand.In 19, the geometry of Cucan be described as five-coordinated distorted square pyramid that exists in a dimer through the weak bonding,and 1-D chain structure is formed by intermolecular hydrogen bonds.

化合物1的单晶结构分析表明1具有四配位平面四边形结构，化合物8是白花丹素的Na盐，以离子化合物形式存在；化合物9～16为白花丹素的La，Y，Dy，Sm，Gd，Nd，Er，Eu的稀土金属配合物；化合物17是白花丹素的双核钇结构；化合物18为白花丹素的单核钇结构，该配合物除了含白花丹素外，还有来自白花丹植物中的另一个单体化合物也参与配位；化合物19～21是以2，2\'-联吡啶和邻菲咯啉等含N配体为辅助配体，具有白花丹素—含N配体—金属离子的三元配合物，化合物19是白花丹素和2，2\'-联吡啶与Cu的配合物，具有五配位的四方锥构型，通过Cu…O弱的成键作用形成二聚体，再通过分子间的氢键作用进一步形成一维链状结构，化合物20和化合物21是白花丹素分别与2，2\'-联吡啶和邻菲咯啉的Zn配合物，都具有六配位八面体构型的双核锌配合物，呈一维链状结构，化合物20中链与链之间的大量氢键将一维链扩展成二维层，分子间的π-π堆积作用进一步形成三维结构。

As we all know,there is one Simson line at any point on the circumference of triangles,but in this paper, LHP theorem shows that the above conclusion is not correct for any quadrilateral pyramid in three-dimensional space and also during proving LHP theorem,fixed value theorem is proved,at the same time,one guess about the point H and point P on circumscribed sphere of tetrahedron has been concluded.

众所周知，三角形的外接圆周上任一点存在一条 simson 线，而 LHP 定理则指出对于正四面体该结论是不能推广到三维空间上的，并且在论证 LHP 定理的过程中得出了定值定理，同时作为一般四面体的外接球球面上的 H 点、P 点的分布，给出了一个猜想。

The town's pre-Hispanic pyramid, crowned today by a church, may have been built in reverence to El Popo; its ancient name, Tlachihualt閜etl, means 'man-made mountain.'"—From "Popocat閜etl, January 1999, National Geographic magazine
