Abstract

The compds. W(CO)5(btd), W(CO)5(bsd and Re(CO)3(bpy)(bsd)(BF4), btd=2,1,3-benzothiadiazole and bsd=2,1,3-benzoselenadiazole were isolated and characterized exptl. (crystal structure, spectroscopy, spectroelectrochem.) and by d. functional theory calcns. The results confirm single N-coordination in all cases, binding to Se was calcd. to be less favorable. Studies of one-electron reduced forms indicate that the N-coordination is maintained during electron transfer. on SciFinder(R)
