Abstract
Abstract A new purple complex of (1,9-diamino-1,4,6,6,9-pentamethyl-3,7-diazanona-3-ene) (l-propylenediamine)nickel(II) perchlorate and the known yellow complex, (octamethyl-1,4,8,11-tetraazacyclotetradecadiene)nickel(II) perchlorate, were obtained by the reaction of tris(l-propylenediamine)nickel(II) perchlorate and acetone without any irradiation by ultraviolet light. The structure of the purple complex was estimated from its absorption and circular dichroism spectra in acetonitril and in an aqueous solution, and from its infrared spectrum in the solid state. The complex was found to take an octahedral [NiN6]-type structure in acetonitril and a planar [NiN4]-type structure in aqueous solution. The (1,9-diamino-1,4,6,6,9-pentamethyl-3,7-diazanona-3-ene)nickel(II) perchlorate and (1,9-diamino-1,4,6,6,9-pentamethyl-3,7-diazanona-3-ene)(ethylenediamine)nickel(II) perchlorate complexes were also prepared.
