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)center dot 6H(2)O with 4,4,10,10-tetramethyl-1,3,7,9-tetraazospiro[5.5]undecane-2,8-dione monohydrate (C11H20N4O2 center dot H2O) in acetone. The crystallographic parameters of I: triclinic structure, sp. gr. P2/c, a = 15.2449(6) , b = 9.2600(3) , c = 18.4205(6) , beta = 103.321(4)A degrees, V = 2530.42(15) (3), Z = 2, C22H64N14O34Co3, d (x) = 1.635 g/cm(3), T = 298 K, R (1) = 0.051 for 3757 F (0) > 4 sigma(F), S = 1.03 to 2 theta(max) = 58.08A degrees. A crystal of I contains octahedral complex cations [Co(H2O)(6)](2+), nitrate anions, and metallopolymer chains of the composition [Co(C11H10N4O2)(H2O)(3)] (n) (2n+) , in which the molecules of the organic ligand are interconnected by binuclear cobalt complexes.
