Abstract :Three metal complexes, [Zninsert ignore into journalissuearticles values(phen);2insert ignore into journalissuearticles values(CH3COO);]insert ignore into journalissuearticles values(ClO4); insert ignore into journalissuearticles values(1);, [Zninsert ignore into journalissuearticles values(bpy);2insert ignore into journalissuearticles values(ClO4);]insert ignore into journalissuearticles values(ClO4); insert ignore into journalissuearticles values(2);, and [Cdinsert ignore into journalissuearticles values(phen);2 insert ignore into journalissuearticles values(NO3);2] insert ignore into journalissuearticles values(3); insert ignore into journalissuearticles values(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, Zninsert ignore into journalissuearticles values(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, Zninsert ignore into journalissuearticles values(II); has pentacoordination geometry with chelating 2 bpy and 1 perchlorato ion. In 3, phen and NO3- serve as bidentate ligands coordinating to Cdinsert ignore into journalissuearticles values(II); through their nitrogen and oxygen atoms to form 8 coordination. Three-dimensional frameworks of complexes 1--3 are produced by hydrogen bonding, and p - p and C-H ... p interactions. Additionally, complexes 1--3 exhibit strong solid state fluorescent emission at room temperature.
