Equimolar quantities of [MoBr(mu-Br) (CO)4}2] and 3,3,7,7,11,11,15,15-octamethyl-1,5,9,13-tetrathiacyclohexadecane (Me8[16]aneS4) in CH2Cl2 at 20-degrees-C gave the novel seven-co-ordinate cation-anion complex [MoBr(CO)2(Me8[16]aneS4)][MoBr3(CO)4] whose molecular structure shows the cation to have a 4:3 'piano-stool' geometry in which the Mo atom lies 1.488(2) angstrom above the plane of the four S atoms, the first example of this structural type.
