A comparative study of the behaviors of 1,1′-bis(selenocyanatomercurio)ferrocene (FBMS) with those of its thiocyanate analog (FBMT), has been made. Various physicochemical studies indicate that the Lewis acids and the adducts formed by FBMS are less stable than those of FBMT. The Dq values of FBMS adducts are higher, but the β values are lower. The matching constant values of FBMT complexes are higher than their corresponding FBMS complexes. The structures of Lewis acids and the adducts are similar in both the cases.
