The crystal structures of 1 and 2 show that the tin atom adopts a distorted trigonal bipyramid geometry via intramolecular carbonyl oxygen to tin coordination [the distances of Sn-0 bond are 0.2351(6) ran for 1 and 0.2362(3) nm for 2]. Compound 1 belongs to monoclinic with space group P2/c, a = 0.9842(2) nm, b =1. 0923(8) nm, c = 1.23948(11) nm,/?= 93.894(15)°, V= 1.3294(4) ran3, Mr = 366.23, 7 = 4. Compound2 belongs to monoclinic with space group P2{/c, a = 1.04443(9) nm, b = 1.04823(7) nm, c = 1.28113(9) nm,/= 90. 953(8)°, V= 1.40239(19) nm3, Mr = 380.25, Z = 4

利用元素分析、红外光谱、核磁共振对其结构进行了表征，并通过X射线单晶衍射测定了1和2的晶体结构，二者均为具有分子内羰基氧原子配位的畸变三角双锥结构。1属于单斜品系，空间群P21/c， a=0.9842(2)nm，b=1.0923(8)nm，c=1.23948(11)nm，β=93.894(15)°，V=1.3294(4) nm^3，Mr=366.23，Z=4.2属于单斜晶系，空间群P21/c，a=1.04443(9)nm，b=1.04823 (7)nm，c=1.28113(9)nm，β=90.953(8)°，V=1.40239(19)nm^3，Mr=380.25，Z=4。

The crystalline defects of metallic substrate can promote the formation of multi-crystal thin films. In contrast, the films on the Si single crystal are basically amorphous; The hardness of films are mainly determined by N concentration. The highest hardnesses of Si〓N〓 and TiN films ware obtained at 1. 1 of N/Si and 0.96 of N/Ti respectively. The hardness of Si〓N〓 film decreased dramatically when the free silicon atoms present.

发现薄膜中N原子百分含量主要受氮离子束流和氮气分压的控制，随着氮离子束流和氮气分压的提高，N/Si和N/Ti原子比增加；膜的组织结构则主要受轰击离子束压和基体种类的影响，高的轰击束压可以抑制薄膜的择优取向，金属基体上的晶体缺陷使薄膜易于形成多晶，而单晶硅上的薄膜基本上为非晶态；薄膜的硬度受氮含量的影响最大。
