Studies of molybdenum-molybdenum bonded species. 1. Synthesis and characterization of a reduction product of Cs/sub 3/Mo/sub 2/Cl/sub 8/H. 2. Mixed sulfur chlorine substituted hexanuclear molybdenum clusters
A black powder isolated from the reaction of Cs/sub 3/Mo/sub 2/Cl/sub 8/H and zinc in refluxing pyridine, Mo/sub 1/ /sub 0/Cl/sub 1/ /sub 1/py/sub 0/ /sub 8/, was studied. The material was amorphous to x-rays, and the infrared spectrum indicated coordinated pyridine and chlorine. The material seemed to be a highly bridged, metal-metal bonded cluster or polymer. Mo/sub 6/Cl/sub 12/ was reacted with various sulfur-containing reagents to prepare mixed chlorine sulfide Mo/sub 6/X/sub 8/ clusters. High reaction temperature with high ratios of NaSH to Mo/sub 6/Cl/sub 12/ (16:1) resulted in decomposition of the Mo/sub 6/X/sub 8/ cluster. Reactions of one equivalent of Mo/sub 6/Cl/sub 12/ and eight equivalents of NaSH at 115/sup 0/C yielded amorphous products. Intermediate conditions produced crystalline Mo/sub 6/X/sub 8/ derivatives. A Fortran IV computer program for analyzing x-ray photoelectron spectra was given. (DP)
