The molecular structures of C33H56P2S4, (1), and C31H56P2, (2), are reported. The structure analysis of (1) is the first of a CS2 adduct of an optically active diphosphine. The optically active compound (1) is not a simple CS2 adduct but contains two zwitterionic structures, i.e. 1,2-cyclopentylenedimethylenebis[(dicyclohexyl)phosphoniocarbodithioate], C5H8[CH2P+(C6H11)(2)(CS2)(-)](2).
