Abstract

Three metal complexes, [Zn(phen)_2(CH_3COO)](ClO_4) (1), [Zn(bpy)_2(ClO_4)](ClO_4) (2), and [Cd(phen)_2 (NO_3)_2] (3) (phen = 1,10-phenanthroline, bpy = 2,2 {Abedini, 2005 #222} -bipyridine), were synthesized and their structures were determined by single-crystal X-ray diffraction analyses. In 1, Zn(II) is coordinated by 4 nitrogen atoms from 2 phen molecules and 2 oxygen atoms from 1 acetato to form an octahedral configuration. In 2, Zn(II) has pentacoordination geometry with chelating 2 bpy and 1 perchlorato ion. In 3, phen and NO_3^- serve as bidentate ligands coordinating to Cd(II) through their nitrogen and oxygen atoms to form 8 coordination. Three-dimensional frameworks of complexes 1--3 are produced by hydrogen bonding, and \pi - \pi and C-H ... \pi interactions. Additionally, complexes 1--3 exhibit strong solid state fluorescent emission at room temperature.
