Abstract:
The cyano-bridged heteronuclear coordination polymer poly[tris[(5,12-dimethyl-7,14-diphenyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene)copper(II)]-hexa-mu-cyano-bis[tricyanocobalt(III)] dimethylformamide solvate trihydrate], {[Cu3Co2(CN)12(C24H32N4)3].C3H7NO.3H2O}n, was synthesized by the assembly reaction of [CuL]2+ (L is 5,12-dimethyl-7,14-diphenyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene) and [Co(CN)6]3- in a dimethylformamide-water solution. The structure consists of neutral cyano-bridged Cu3Co2 units with the unique Co atom in a general position and all three Cu atoms on independent inversion centres. Each [Co(CN)6]3- ion connects three CuII ions via three cyano groups to form a novel cyano-bridged two-dimensional stair-shaped-layer structure. The water and dimethylformamide molecules are situated in the inter-fragment spaces.

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...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
