Synthesis and X-ray Crystallographic and Spectroscopic Study of Dichlorobis{spiro[cyclopentane-1 ',-3-(1-(4 ',4 '-dimethyl-2 ',6 '-cyclohexanedion-1 '-ylidene)-1,2,3,4-tetrahydroisoquinoline-O)]}cobalt(II)

The new complex [CoL(2)(1)Cl(2)] (I), where L(1) is spiro[cyclopentane-1',3-(1-(4',4'-dimethyl-2',6'- cyclohexanedion-1'-ylidene)-1,2,3,4-tetrahydroisoquinoline)], was synthesized. The X-ray crystal structure of I was determined (3062 independent reflections, R = 0.0406, a = 26.690(5) angstrom, b = 12.959(3) angstrom, c = 23.339(5) angstrom, beta = 90.65(3)degrees, space group C2/c, Z = 8). Interatomic distances, bonds angles, and conformations of the molecule of ligand L(1) in complex I are as a whole close to those of 3,3-dimethyl- (L(2)) and spiro{cyclohexane-1',3-(L(3)) 1-(4',4'-dimethyl-2',6'cyclohexanedion-1'-ylidene)-1,2,3,4-tetrahydroisoquinolines in the previously studied complexes [CuL(2)Cl(2)](n) (II) and [CuL(3)Cl(2)](n) center dot nH(2)O (III). The occurrence of the Co(II) atom instead of the Cu(II) atom in I leads to changes in the ligand coordination mode: L(1) is monodentately coordinated to the Co(II) atom via one of the oxygen atoms of the cyclohexanedione fragment. The M : L molar ratio in I differs from that in II and III (1 : 2 in I and 1 : 1 in II and III), although the conditions of the synthesis are the same (metal : ligand ratio, acetone, 20 degrees C. This complex is characterized by IR and electronic absorption spectroscopy data.
