Four NiII complexes with the new cyclam-methylimidazole ligand 1-[(1-methyl-1H-imidazol-2-yl)methyl]-1,4,8,11-tetraazacyclotetradecane
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-t...
