Abstract
A one-dimensional chain complex, {[Co(bpm)2(N3)2][Co(bpm)2(H2O)2]} (ClO4)2, (bpm being bis(pyrazol-l-yl)methane), has been synthesized and characterized by X-ray diffraction: triclinic, space group P - 1 with a = 8.805(2) A, b = 8.902(2) A, c = 13.621(3) A, α = 84.27(3)°, β = 84.63(3)°, γ = 80.05(3)°, V = 1043.2(4) A3, Z = 1. Two cobalt atoms have ideal octahedral environments with different coordination atoms. One cobalt atom is six-coordinated with nitrogen atoms from two bpm ligands and two azide ligands, while the other cobalt atom is coordinated by four nitrogen atoms from bpm and two oxygen atoms from water molecules. The complex forms one-dimensional chain through hydrogen bonds.
