Abstract
Eight complexes with different 3d metal centers and auxiliary ligands, [Cu(L)(py)] (1), [Cu(L)(bpy)]·1.5H2O (2), [Mn(L)] (3), [Mn(L)(pybim)]·3H2O (4), [Ni(L)(bpy)]·2H2O (5), [Ni(L)(phen)]·2H2O (6), [Ni(L)(bpe)(H2O)]·2H2O (7) and [Zn(L)(bpy)]·2H2O (8) [H2L=5-(imidazol-1-ylmethyl)isophthalic acid, py=pyridine, bpy=2,2′-bipyridine, pybim=2-(pyridin-2-yl)-1H-benzo[d]imidazole, phen=1,10-phenanthroline, bpe=1,2-di(pyridin-4-yl)ethylene] were obtained under hydrothermal conditions and characterized by single crystal and powder X-ray diffractions, IR, elemental and thermogravimetric analyses. Complex 1 is a 3-connected uninodal 2D network with (4.82) topology, while 2, 4, 6 and 7 display 3-connected uninodal 2D network with (63) hcb topology, 3 exhibits a (5,5)-connected binodal 3D net with (45)(65) topology, 5 and 8 have 1D double-chain structures. The influence of metal centers and auxiliary ligands on the structures of resultant complexes is discussed. Magnetic property of 3 and luminescence of 8 were investigated.
