Coordination Polymer Based on Nickel(II) Maleate and 4′-Phenyl-2,2′:6′,2"-Terpyridine: Synthesis, Crystal Structure and Conjugated Thermolysis

New complex (1) based on nickel(II) maleate and 4 '-phenyl-2,2 ':6 ',2 ''-terpyridine (L) was synthesized. The complex 1 is a 1D coordination polymer formed from a L-Ni(II) node bridged by maleate ligands and crystallizes in monoclinic form with space group P2(1)/n. There are two Ni(II) moiety's in the asymmetric unit. Each nickel atom is five coordination and is chelated by three nitrogen atoms of L and two oxygen atoms of Mal fragments with the formation of a NiN3O2 chelate node. The polyhedron of the first Ni(II) moiety is close to the ideal tetragonal pyramidal structure, while the polyhedron of the second Ni(II) moiety belongs to the distorted tetragonal pyramidal structure. The main stages and kinetics features of the conjugated thermolysis of complex 1 were evaluated. Metal-polymer nanocomposite containing Ni nanoparticles uniformly distributed in a stabilizing nitrogen-containing polymer matrix was obtained.
