| Abstract: | Taking Cu(2-mpac)2(H2O)]•3H2O (2-mpac＝5-methyl-2-pyrazinecarboxylic acid) (1) as the ligand of a complex, a novel Cu-Cd heterometallic coordination polymer, Cu(2-mpac)2(H2O)2Cd(H2O)4- (NO3)2]n (2) has been successfully synthesized and structurally characterized by an X-ray single crystal diffraction method. Crystal data: triclinic, space group P-1, a＝0.7654(7) nm, b＝0.8903(8) nm, c＝0.9745(9) nm, α＝116.116(1)°, β＝98.408(1)°, γ＝90.335(1)°, V＝0.5880(9) nm3, Z＝1, S＝1.053, final R indices I＞2σ(I)] R1＝0.0280, wR2＝0.0718, for all reflections R1＝0.0305, wR2＝0.0741. In addition, elemental analysis and IR characterization were presented. |
