摘要：
Single crystal X-ray diffraction is used to determine the crystal structure of the coordination metallopolymer {[Co(C11H20N4O2)(H2O)3], [Co(H2O)6](NO3)4}n (I), which is prepared by reacting Co(NO3)2·6H2O with 4,4,10,10-tetramethyl-1,3,7,9-tetraazospiro[5.5]undecane-2,8-dione monohydrate (C11H20N4O2·H2O) in acetone. The crystallographic parameters of I: triclinic structure, sp. gr. P2/c, a = 15.2449(6) Å, b = 9.2600(3) Å, c = 18.4205(6) Å, β = 103.321(4)°, V = 2530.42(15) Å3, Z = 2, C22H64N14O34Co3, dx = 1.635 g/cm3, T = 298 K, R1 = 0.051 for 3757 F0 > 4σ(F), S = 1.03 to 2θmax = 58.08°. A crystal of I contains octahedral complex cations [Co(H2O)6]2+, nitrate anions, and metallopolymer chains of the composition [Co(C11H10N4O2)(H2O)3]n2n+, in which the molecules of the organic ligand are interconnected by binuclear cobalt complexes.
