Abstract:
The asymmetric unit of the title compound, [Co2(NCS)4(C10H8N2)3(C2H6OS)2] n , consists of one Co(II) atom, two thio-cyanate anions, one dimethyl sulfoxide mol-ecule and one and a half 4,4'-bi-pyridine mol-ecules. The half-molecule is completed by inversion symmetry. The Co(II) atom is coordin-ated in a distorted octa-hedral geometry by two N atoms from two thio-cyanate anions, one O atom from dimethyl sulfoxide as a terminal ligand and three N atoms from three 4,4'-bi-pyridine mol-ecules as bridging ligands linking the cations, with a Co⋯Co separation of 11.5964 (5) Å. This generates a two-dimensional structure parallel to (-103). A C-H⋯S hydrogen bond links the layers into a three-dimensional supra-molecular framework. The layers are stacked in an ABC fashion preventing the occurrence of inter-layer void space and hence leading to the absence of lattice solvent and/or organic guest mol-ecules in the structure.

Valence Bond Theory
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...
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...
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,...
