The first known simple thiocyanato metal carbonyl, Mn(CO)5SCN, was prepared by the reaction of NaMn(CO)5 with ClSCN in tetrahydrofuran (1). This golden yellow compound, soluble in chloroform, acetone and methanol, is diamagnetic and a nonelectrolyte in nitromethane. Its IR spectrum in the 1900 – 2200 cm-1 region is consistent with a distorted C4v symmetry. The distortion probably arises from nonlinearity of the Mn — S- CN moiety and suggests a sulfur-bonded structure (2). This mode of attachment is supported by the CS stretching frequency, which occurs at 676 cm-1 and is diagnostic of an S -bonded thiocyanate (3).
