The asymmetric unit of the title compound, [PdCl(C9H12NSe)(C18H15P)], contains two independent mol-ecules. In both cases, the Pd(2+) cations are coordinated by the Se and N atoms of the chelating bidentate 2-[(di-methyl-amino)-meth-yl]benzene-seleno-late ligand. The chloride ligand lies trans to selenium and the tri-phenyl-phosphane ligand is trans to nitro-gen. The Pd-Se bond lengths in the two independent coordination environments of Pd are 2.3801 (4) and 2.3852 (4) Å, the Pd-P bond lengths are 2.2562 (8) and 2.2471 (8) Å, the Pd-N bond lengths are 2.172 (2) and 2.158 (2) Å, and the Pd-Cl bond lengths are 2.3816 (8) and 2.3801 (8) Å. The square-planar coordination around one Pd(2+) cation is less distorted than that around the other.
标题化合物[PdCl(C₉H₁₂NSe)(C₁₈H₁₅P)]的不对称单元包含两个独立分子。在这两种情况下,Pd(2+)阳离子均由螯合双齿2-[(二甲基氨基)甲基]苯硒酸酯配体的Se和N原子配位。氯配体与硒处于反位,三苯基膦配体与氮处于反位。在Pd的两个独立配位环境中,Pd-Se键长分别为2.3801(4)和2.3852(4) Å,Pd-P键长分别为2.2562(8)和2.2471(8) Å,Pd-N键长分别为2.172(2)和2.158(2) Å,Pd-Cl键长分别为2.3816(8)和2.3801(8) Å。一个Pd(2+)阳离子周围的平面正方形配位比另一个的扭曲程度小。
