Abstract: Two new polymorphs of the title compound, K[PtCl₃(C₆H₁₅O₄PS)], already known in the monoclinic form, were obtained by crystallization from acetone-n-pentane solutions of different composition. Both polymorphs are orthorhombic in the space group P2₁2₁2₁, with Z' = 1 (solvent ratio 1:4) and 3 (solvent ratio 1:9). In both polymorphs, electrostatic interactions link K⁺ cations and [PtCl₃(SMP)]^- anions [SMP is diethyl (methylsulfinylmethyl)phosphonate] in infinite chains, while adjacent chains are held together by weak C-HCl and C-HO hydrogen-bond interactions.

Formula: Two polymorphs of K[PtCl₃(C₆H₁₅O₄PS)]
