Abstract
The hydrothermal reaction of Cd(II) salt with 5-[(2-methyl-1H-imidazol-1-yl)methyl]isophthalic acid (H2L) leads to the formation of a new complex [Cd(L)(H2O)] (1). While in the presence of 2,2′-bipyridine (bpy) and 1,10-phenanthroline (phen) as auxiliary ligands, complexes [Cd(L)(bpy)]∙H2O (2) and [Cd(L)(phen)]∙2H2O (3) were obtained. Complexes 1–3 have been characterized by single crystal and powder X-ray diffractions, IR, and elemental and thermogravimetric analyzes. As a result, complex 1 exhibits twofold interpenetrated 3-D (10,3)-a architecture, 2 displays chain structure, and 3 shows uninodal 3-connected hcb network with (63) topology. The impact of auxiliary ligands on the structures of resultant complexes is discussed. Moreover, luminescence property of 1–3 was investigated.
