부경대학교 화학과,
Two new nickel(II) complexes of the composition [Ni(cyclam)(Hdipic)2]∙2H2O (1) and [Ni(cyclam)(H2O)2][Ni(dipic)2]∙2.5H2O (2) (dipic = 2,6-pyridinedicarboxylate, dipicolinate) have been prepared and structurally characterized. The structure of 1 shows that the central nickel(II) ion is coordinated axially by two monodentate Hdipic ligands. The discrete neutral complex 1 further extends its structure by hydrogen bonding interactions to form a one-dimensional supramolecule. The structure of 2 consists of two independent nickel(II) centers. Water molecules instead of dipic ligands prefer to coordinate to the Ni1 ion forming a dication. Two dipic ligands coordinate to the second Ni2 ion forming a dianion. The dications and dianions are charge-balanced, resulting in a molecular salt. Details of the structures of 1 and 2 as well as their spectroscopic and thermal properties will be described in this work.
