The title compound compound [cis-{C6H5(C2H5)2P}2PtCl2] has been obtained as yellow powder in the reaction of a solution of phenyl(diethyl)phosphane in ethanol with a solution of potassium tetrachloroplatinate(II) in water (Matern et al., 2000). Slow crystallization from THF at ambient temperature yielded crystals suitable for X-ray analysis.
All C–H hydrogen atoms were refined as riding on carbon atoms with methyl C–H = 0.98 Å, methylen C–H = 0.99 Å, aromatic C–H = 0.95 Å and Uiso(H) = 1.2 Ueq(C) for aromatic CH, 1.3 for CH2 groups and 1.5 for methyl groups.
We have a standing interest in the reactivity of [(R3P)2PtCl2] compounds towards diphosphanes (Domanska-Babul, Chojnacki, Matern & Pikies, 2007). The title compound, [(Et2PhP)2PtCl2], was obtained according to the published procedure (Matern et al., 2000) and recovered from the reaction mixture during the studies.
An ORTEP plot of the title compound is shown in Fig. 1. The geometry of the Pt atom is slightly distorted square planar with the metal displaced by only 0.0007 (2) Å from the PtCl2P2 mean plane. The Cl and P atoms display a substantial tetrahedral distortion, being displaced by 0.1647 (13), -0.1394 (13), -0.1349 (13) and 0.1267 (12) Å for Cl1, Cl2, P1 and P2 respectively. For comparison, the displacements found for the same atoms in the related complex [(EtPh2P)2PtCl2] (Domanska-Babul, Chojnacki & Pikies 2007) are -0.0238 (5), -0.0008 (5), -0.0251 (5) and -0.0060 (5) Å respectively. Even more significant departures from planarity are observed in the case of sterically demanding phosphanes ligands, viz. in [cis-(tBu2PhP)2PtCl2] (Porzio et al., 1980). The bond angle P1–Pt–P2 of 94.43 (4)° indicates steric repulsion of the PhEt2P groups smaller than those observed for the EtPh2P groups in [(EtPh2P)2PtCl2] (100.23 °) and for the MePh2P groups in [(MePh2P)2PtCl2] (98.11 °; Ho et al., 1982). The average Pt–P and Pt–Cl distances of 2.253 (13) Å and 2.356 (12) Å respectively are typical for [cis-(R3P)2PtCl2] complexes. The dihedral angles formed by the C1—C6 and C11—C16 phenyl rings with the PtCl2P2 mean plane are 82.21 (11) and 79.98 (11) ° respectively. The crystal structure is reinforced by weak intra- and intermolecular C—H···Cl hydrogen interactions (Table 1).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

We have a standing interest in the reactivity of [(R3P)2PtCl2] compounds towards diphosphanes (Domanska-Babul, Chojnacki, Matern & Pikies, 2007). The title compound, [(Et2PhP)2PtCl2], was obtained according to the published procedure (Matern et al., 2000) and recovered from the reaction mixture during the studies.
An ORTEP plot of the title compound is shown in Fig. 1. The geometry of the Pt atom is slightly distorted square planar with the metal displaced by only 0.0007 (2) Å from the PtCl2P2 mean plane. The Cl and P atoms display a substantial tetrahedral distortion, being displaced by 0.1647 (13), -0.1394 (13), -0.1349 (13) and 0.1267 (12) Å for Cl1, Cl2, P1 and P2 respectively. For comparison, the displacements found for the same atoms in the related complex [(EtPh2P)2PtCl2] (Domanska-Babul, Chojnacki & Pikies 2007) are -0.0238 (5), -0.0008 (5), -0.0251 (5) and -0.0060 (5) Å respectively. Even more significant departures from planarity are observed in the case of sterically demanding phosphanes ligands, viz. in [cis-(tBu2PhP)2PtCl2] (Porzio et al., 1980). The bond angle P1–Pt–P2 of 94.43 (4)° indicates steric repulsion of the PhEt2P groups smaller than those observed for the EtPh2P groups in [(EtPh2P)2PtCl2] (100.23 °) and for the MePh2P groups in [(MePh2P)2PtCl2] (98.11 °; Ho et al., 1982). The average Pt–P and Pt–Cl distances of 2.253 (13) Å and 2.356 (12) Å respectively are typical for [cis-(R3P)2PtCl2] complexes. The dihedral angles formed by the C1—C6 and C11—C16 phenyl rings with the PtCl2P2 mean plane are 82.21 (11) and 79.98 (11) ° respectively. The crystal structure is reinforced by weak intra- and intermolecular C—H···Cl hydrogen interactions (Table 1).
