The crystal structure of cis-[PtCl2(C6H15As)(2)], (I), is isostructural wit
h a previously reported structure of cis-[PtCl2-(C6H15P)(2)],(II). A new po
lymorph of (II) is also reported here. Selected geometrical parameters in t
he arsine complex are Pt-Cl 2.3412 (12) and 2.3498 (13), Pt-As 2.3563 (6) a
nd 2.3630 (6) Angstrom, Cl-Pt-Cl 88.74 (5), As-Pt-As 97.85 (2), and Cl-Pt-A
s 171.37 (4) and 177.45 (4)degrees. Corresponding parameters in the phosphi
ne complex are Pt-Cl 2.364 (2) and 2.374 (2), Pt-P 2.264 (2) and 2.262 (2)
Angstrom, Cl-Pt-Cl 85.66 (9), P-Pt-P 98.39 (7), and Cl-Pt-P 170.26 (7) and
176.82 (8)degrees.
