“…Compound I was obtained from Co(NO 3 ) 2 ⋅6H 2 O (chemically pure grade), Sk⋅H 2 O prepared by the techniques [16,17], and acetone (high purity grade). Cobalt nitrate was first dissolved in a small volume of acetone; then, spirocarbone was added in a 1:2 molar ratio.…”

{[Co(C 11 H 20 N 4 O 2 )(H 2 O) 3 ], [Co(H 2 O) 6 ](NO 3 ) 4 } n V. V. Dotsenko and E. E. Netreba UDC 548.737:546.732:547.853.3 Single crystal X-ray diffraction is used to determine the crystal structure of the coordination metallopolymer {[Co(C 11 H 20 N 4 O 2 )(H 2 O) 3 ], [Co(H 2 O) 6 ](NO 3 ) 4 } n (I), which is prepared by reacting Co(NO 3 ) 2 ⋅6H 2 O with 4,4,10,10-tetramethyl-1,3,7,9-tetraazospiro[5.5]undecane-2,8-dione monohydrate (C 11 H 20 N 4 O 2 ⋅H 2 O) 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) Å 3 , Z = 2, C 22 H 64 N 14 O 34 Co 3 , d х = 1.635 g/cm 3 , T = 298 K, R 1 = 0.051 for 3757 F 0 > 4σ(F), S = 1.03 to 2θ max = 58.08°. A crystal of I contains octahedral complex cations [Co(H 2 O) 6 ] 2+ , nitrate anions, and metallopolymer chains of the composition [Co(C 11 H 10 N 4 O 2 )(H 2 O) 3 ] 2n n + , in which the molecules of the organic ligand are interconnected by binuclear cobalt complexes.Carbamide derivative coordination compounds with bidentate bridging ligands containing heterocyclic condensed spirocycles are very poorly understood in terms of their physical activity. One of these derivatives of the spirobiscycloundecane class is 4,4,10,10-tetramethyl-1,3,7,9-tetraazospiro-[5.5]undecane-2,8-dione, or spirocarbone (Sk) (Scheme 1): Scheme 1.Spirocarbone is of interest to researchers in different fields for its valuable biological properties: low toxicity (LD 50 = 3000 mg/kg) [1], membrane trophic action [2], and accumulation in murine leukemia cells of L1210 line and human leukemia cells of CEM-T4 [3]. There is evidence that Sk affects the physicochemical and functional properties of hemoglobin and the antioxidant system regulating intracellular processes through NO • and its derivatives [4]. Spirocarbone can increase protein and reduce starch in oat and barley grains [5,6]. Studies [7,8] confirmed the effectiveness of Sk in stimulating callus
