Bis(2-chloro-1,10-phenanthroline-κN,N')(thio-cyanato-κN)zinc
Abstract:
The asymmetric unit of the title compound, [Zn(NCS)(C(12)H(7)ClN(2))(2)][Zn(NCS)(3)(C(12)H(7)ClN(2))], contains two cations and two anions. In the cations, the Zn(II) ions have distorted trigonal-bipyramidal environments formed by four N atoms from two 2-chloro-1,10-phenanthroline (cphen) ligands and one N atom from a thio-cyanate ligand. The Zn(II) atoms in the complex anions also have distorted trigonal-bipyramidal environments, formed by two N atoms from a cphen ligand and three N atoms from three thio-cyanato ligands. The crystal packing exhibits π-π inter-actions between the rings of the cphen ligands [shortest centroid-centroid distance = 3.586 (5) Å] and short inter-molecular S⋯Cl [3.395 (5) Å] and S⋯S [3.440 (4) Å] contacts.

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...

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...
