Abstract

The gold, paramagneti~'~ molybdate from eq 1 (mp 110-111 "C dec) exhibited infrared absorbances due to the terminal oxo ligand at 993 cm-' and due to terminal and bridging chlorides, respectively, at 360 and 308 cm-'. Thus, the Mo202C17- anion in this species appears to have the usual14 triply bridged structure of M2X9 dimers, with chloride ligands constituting all three of the bridges. The white, diamagnetic hexachloroantimonate salt exhibited the ...
