Özet

Three metal complexes, [Zn(phen)(2)(CH3COO)](ClO4) (1) [Zn(bpy)(2)(ClO4)](ClO4) (2), and [Cd(phen)(2)(NO3)(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 NO3- 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.
