The title compound, C14H11Cl2OP, was synthesized by the reaction of diphenylphosphine oxide with 1,2-dichloroethyne under CuI catalysis. The reaction provided the Z isomer regioselectively. Two O-P-C bond angles [114.3 (1) and 112.5 (1)degrees] are significantly larger than the C-P-C [107.7 (1), 105.6 (1) and 106.6 (1)degrees] and another O-P-C angle [109.5 (1)degrees], indicating significant distortion of the tetrahedral configuration of the P atom. In the crystal, molecules are linked by weak intermolecular C-H center dot center dot center dot O hydrogen bonds into centrosymmetric dimers, which are connected by further C-H center dot center dot center dot O interactions into chains along [101].
