The complex of Cu [CH2 C (CH3) COO] 2 (C7H6N2) 2 (1) and the green dinuclear cage complex Cu2 [CH2 C (CH3) COO] 4 (C7H6N2) 2 (2). The crystal structure was characterized by elemental analysis and IR spectra and electron reflectance spectroscopy. The crystal of complex 1 belongs to monoclinic system with space group P2 1 / c, a = 0.92 41 6 (8) nm, b = 1 .2 330 2 (1 3) nm, c = 0 .9891 (3) nm, β = 91 .91 2 (1 3) °, DC = 1 The complex 2 crystal belongs to monoclinic system, the space group P2 1 / c, a = 0.90 5 7 (2) nm, b = 2.2 5 2 1 (5) nm, c = 1.6235 (4) nm, β = 90.1 1 (2) °, DC = 1.41 1g / cm3, Z = 4, R = 6 8, Cu-Cu bond length was 0.226 6 1 (7) nm. The formation mechanism of the two complexes was discussed.
