Abstract:	The structure of the compound Fe₄(CO)₁₂S(CSNMe₂)(CNMe₂) has been determined by X-ray crystallography. The compound crystallizes in space group P2₁/c with four molecules in a unit cell of dimensions a 8.840(2), b 20.174(9), c 16.856(5)Å, β 114.82(3)°. Full-matrix least-squares refinement of 2881 counter data yielded R = 0.046. The molecule consists of two Fe₂(CO)₆ units bridged by thiocarboxamido and immoniocarbene ligands and by a common bridging sulfur atom. The structure of this compound is compared with those of related molecules and a detailed comparison is made of the bonding properties of the thiocarboxamido ligand in bridging and chelating configurations.
