Abstract:
The title manganese(III) phthalocyaninate (Pc) complex, viz. iodo[phthalocyaninato(2-)]manganese(III) hemi(diiodine), [Mn(C32H16N8)I].0.5I2 or (MnPcI)2.I2, was obtained from the reaction of pure powdered manganese with phthalonitrile under oxidation conditions of iodine vapour. The phthalocyaninato(2-) residue is not strictly planar and the Mn atom is five-coordinate, having distorted square-pyramidal geometry and residing 0.262 (2) A above the plane defined by the four isoindole N atoms of the phthalocyaninate macrocycle. The neutral I2 molecule bridges the iodo[phthalocyaninato(2-)]manganese(III) molecules, forming a centrosymmetric dimeric structure.

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, SCN− can be...
