Inorganic-organic hybrid metal complexes: 24-membered hexaazamacrocyclic dinuclear nickel complexes hybridized with CdBr42- Academic Article uri icon


  • The 24-membered macrocyclic mononuclear cadmium complex reacts with Ni(ClO4)2 in solution and unexpected dinuclear nickel complex was obtained with [CdBr4]2- as counter ions. In the homodinuclear nickel complex, two different coordination environmental entities were observed. One of these is a five-coordinated dinuclear species, the other is a six-coordinated dinuclear species [Ni(1A)2C26H40N6 O2(H2O)2]. In [Ni(1A)2C26H40N6 O2(H2O)2], nickel ion is coordinated to three nitrogen atoms, one phenolic oxygen from the macrocyclic ligand, and with one exogenous water molecule to complete an octahedron. In [Ni(1B)2C26H40N6O2], each nickel ion is five-coordinated without solvent interaction. [CdBr4]2- anions are located in the lattice and serve as hybrid bridges to connect two different molecules and form two layer arrays along the c axis. The whole molecule is described as an ion pair with a two-dimensional hydrogen bonding network. The average bond lengths of Ni-N and Ni-O(phenolic oxygen) are 2.083, 2.028 . 2002 Elsevier Science B.V. All rights reserved.
