Ｎｉ（ＮＨ３）３Ａｇ（ＳＣＮ）３晶体的空间群是Ｐｂｎ２１，其晶胞参数为：ａ＝９．４４２（１），ｂ＝１７．３４４ （５），ｃ＝２２．４８４（２）Ａ；Ｚ＝１２（ρｏｂｓ.＝２.１５ｇ·ｃｍ－３，ρｃａｌｃ.＝２．１２ｇｃｍ－３）．晶胞内有 三套对称性独立的Ｎｉ和Ａｇ．其中两个Ａｇ原子由Ｓ原子形成四面体配位，且这两个四面体通过共棱 联系．第三个Ａｇ原于由Ｓ原于形成四角锥五配位．四角锥与两个共棱四面体通过共点联成无穷骨 架．在晶体中，每个Ｎｉ原子分别由三个ＳＣＮ的Ｎ原子和三个ＮＨ３的Ｎ原子按八面体配位，其中有 两个Ｎｉ原子的配位体按顺式排布，第三个 Ｎｉ原子的配位体却是反式排布的。硫氰酸根作为桥配位 体将两类金属原子联在一起．
The space group of Ni (NH3) 3Ag (SCN) 3 crystals is Pbn21, with unit cell parameters of a = 9.442 (1), b = 17.344 (5) and c = 22.484 Z = 12 (ρobs. = 2.15 g · cm -3, ρ calc. = 2.12 g cm -3). There are three symmetrical sets of Ni and Ag in the unit cell. Two of these Ag atoms form a tetrahedral coordination by S atoms, and the two tetrahedra are connected by a common prism. The third Ag originated from the S originates from the formation of tetrapod five coordination. The quadrangular pyramid and the two co-prismatic tetrahedra form a infinite skeleton through a total of points. In the crystal, each Ni atom is octahedrally coordinated by N atoms of three SCNs and N atoms of three NH3s, respectively. Two of the Ni atoms are arranged in a cis arrangement, and a third Ni atom The ligand is trans arrangement. Thiocyanate as a bridge ligand will be two types of metal atoms linked together.
