Inorganic Coordination Polymers. XXI. Manganese (II), Cobalt (II), Nickel (II), Copper (II), and Zinc (II) Bis(N-Phenylaminomethyl) Phosphinates. Effects of Coordinating Side Groups.
Abstract
The metal (II) bis(bis(N-phenylaminomethyl)phosphinates) M(OP(CH2NHC6H))2-O)2 (with M = Mn, Co, Ni, Cu, and Zn) have been investigated. The manganese, cobalt and nickel derivatives all have similar structures with octahedrally coordinated metal centers, the copper derivative is probably tetragonally distorted octahedral, and the zinc derivative is tetrahedral, All of these compounds contain some coordinating amine groups except the zinc complex in which no amine groups coordinate. Most likely, all of these compounds contain symmetrically bridging O,O' phosphinate groups. The thermal stabilities of these complexes are markedly different from one another and a appear to be dependent on the ligand field stabilization energies but not on the chelation of the amine groups.
