Abstract: In the title complex, [PtCl₂(C₁₀H₁₆NO₃P)₂]·0.5H₂O, two diethyl 2-pyridylmethylphosphonate (pmpe) ligands are coordinated to the Pt atom via their pyridyl N atoms. Two cis-chloro ligands complete the distorted square-planar Pt coordination environment. The two pmpe ligands exhibit significantly different conformations. Some atoms in ethoxy groups are positionally disordered. In the crystal structure, a water molecule is found with half-occupancy. Apart from typical hydrogen-bond O(water)-HO interactions, weak C-HO and C-HCl contacts are also observed.
