Abstract

The mononuclear complex (NMe_4)_3[Re(η^2-CS_3)_4] has been prepared by adding CS_2 to ReS^−_4 in a mixture of MeOH and NH_3. During the reaction, Re^VII is reduced to Re^V, the measured diamagnetism (X = -3.04 × 10^−4cm^3mol^−1) of the complex showing that the two added electrons are coupled. (NMe_4)_3[Re(η^2-CS_3)_4] crystallizes in the space group Fddd, a = 11.985(4) Å, b = 23.001(11) Å, c = 47.463(19) Å, V = 13085(9) Å^3. The reaction of CS_2 results in the formation of trithiocarbonates bonded to the rhenium in a dodecahedral geometry.
