Synthesis, characterization and crystal structure of a novel Ni(II) coordination polymer with dipyrido[3,2-a:2 ',3 '-c]phenazine and 4,4 '-oxy(bisbenzoate)

摘要

A novel coordination polymer, [Ni(dppz)(oba)(H2O)]center dot 0.5H(2)O (dppz = dipyrido[3,2-a:2',3'-c]phenazine and oba = 4,4'-oxy(bisbenzoate)) has been synthesized through hydrothermal method and characterized by IR, and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 23.163(5), b = 18.211(4), c = 14.460(3) angstrom, alpha = gamma = 90 degrees, beta = 100.45(3)degrees, V = 5998(2) angstrom(3), Z = 2. The structure was solved by direct methods and refined to R = 0.0866 (wR(2) = 0.1836). The compound exhibits interesting one-dimensional chain structures, which are further stacked through pi-pi interactions to form supramolecular double chains.
