Abstract:
Although it has not proved possible to crystallize the newly prepared cyclam-methylimidazole ligand 1-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8,11- tetra-aza-cyclo-tetra-decane (L Im1), the trans and cis isomers of an NiII complex, namely trans-aqua-{1-[(1-methyl-1H-imidazol-2-yl) methyl]-1,4,8,11-tetra-aza-cyclo-tetra-decane}nickel(II) bis-(perchlorate) mono-hydrate, [Ni(C15H30N6)(H 2O)](ClO4)2·H2O, (1), and cis-aqua-{1-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8,11-tetraaza-cyclo-tetra- decane}nickel(II) bis-(perchlorate), [Ni(C15H30N 6)(H2O)](ClO4)2, (2), have been prepared and structurally characterized. At different stages of the crystallization and thermal treatment from which (1) and (2) were obtained, a further two compounds were isolated in crystalline form and their structures also analysed, namely trans-{1-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8,11- tetra-aza-cyclo-tetra-decane}(perchlorato)nickel(II) perchlorate, [Ni(ClO 4)(C15H30N6)]ClO4, (3), and cis-{1,8-bis-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8,11-tetra-aza-cyclo- tetra-decane}nickel(II) bis-(perchlorate) 0.24-hy-drate, [Ni(C 20H36N6)](ClO4)2· 0.24H2O, (4); the 1,8-bis-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8, 11-tetra-azacyclo-tetra-decane ligand is a minor side product, probably formed in trace amounts in the synthesis of LIm1. The configurations of the cyclam macrocycles in the complexes have been analysed and the structures are compared with analogues from the literature. © 2012 International Union of Crystallography.
