Bis[tris-(1,10-phenanthroline)nickel(II)] tris-[dicyanidoargentate(I)] nitrate 4.2-hydrate
Abstract:
The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H⋯O and C-H⋯N inter-actions may help to establish the packing.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
