Crystal structures and thermal properties of two transition-metal compounds {[Ni(DNI)2(H2O)3][Ni(DNI)2 (H 2O)4]}•6H2O and Pb(DNI)2(H 2O)4 (DNI = 2,4-Dinitroimidazolate)
Two transition-metal compounds derived from 2,4-dinitroimidazole, {[Ni(DNI)2(H2O)3][Ni(DNI)2(H 2O)4]}•6H2O, 1, and Pb(DNI) 2(H2O)4, 2, were characterized by elemental analysis, FT-IR, TG-DSC and X-ray single-crystal diffraction analysis. Crystal data for 1: monoclinic, space group C2/c, a = 26.826(3...
