Abstract: The crystal structure of cis-[PtCl₂(C₆H₁₅As)₂], (I), is isostructural with a previously reported structure of cis-[PtCl₂(C₆H₁₅P)₂], (II). A new polymorph of (II) is also reported here. Selected geometrical parameters in the arsine complex are Pt-Cl 2.3412 (12) and 2.3498 (13), Pt-As 2.3563 (6) and 2.3630 (6) Å, Cl-Pt-Cl 88.74 (5), As-Pt-As 97.85 (2), and Cl-Pt-As 171.37 (4) and 177.45 (4)°. Corresponding parameters in the phosphine complex are Pt-Cl 2.364 (2) and 2.374 (2), Pt-P 2.264 (2) and 2.262 (2) Å, Cl-Pt-Cl 85.66 (9), P-Pt-P 98.39 (7), and Cl-Pt-P 170.26 (7) and 176.82 (8)°.

Formula: [PtCl₂(C₆H₁₅As)₂] and [PtCl₂(C₆H₁₅P)₂]
