Cu(NH3)2Ag(SCN)3是深绿色六方柱状(或六方双锥)晶体.通过X射线研究确定晶体的空间群为P62c;共晶胞参数为:a=9.22Å,c=7.38Å;晶胞内含有两个{Cu(NH3)2Ag(SCN)3)(ρobs=2.308克/厘米3,ρealc=2.319克/厘米3).晶体的结构是通过Patterson函数投影P0(u,v),P0(u,w)和电子密度投影ρ0(x,z)的计算进行测定的.在这个晶体结构中,Ag原子由6个S原子按八面体型配位方式直接配位;每两个AgS6八面体通过由三个S原子所组成的共面互相衔接,沿着c轴无限延伸.SCN的另一端N原子与cu原子形成正三角型配位,CuN3上下又排布着两个NH3分子,使Cu具有三方双锥的配位构型.这样,SCN利用其两端原子把Ag与Cu联系起来,使晶体具有三维骨架型的结构.

An X-ray examination of the deep-green-coloured, hexagonal-prismatic or hexagonalbipyramidal-shaped crystals of the di-ammine complex of copper (Ⅱ) silver (I) trithiocyanate, obtained on mixing CuSO4 and K2Ag(SCN)3 in a dilute ammoniacal solution, gives the following crystallographic data: a=9.22Å,c=7.38Å, containing two Cu(NH3)2Ag (SCN)3 per unit cell (ρobs=2.308g/cm3, ρealc=2.319g/cm3).
