摘要
三苯基膦(PPh3)取代了[PdCl2(CH3CN)2]中的乙腈，随后加入氰酸钾导致氯配体被NCO-取代，生成反式-[Pd(NCO)2(PPh3)2]。通过元素分析、红外光谱和单晶x射线衍射对配合物进行了表征。该化合物在三斜晶系中结晶，空间群P1的a = 9.213(3) a, b = 9.781(7) a, c = 10.483(5) a， α = 111.39(5)°，β = 93.49(3)°，γ = 103.81(4)°，V = 845.0(1)A3, Z = 1。该配合物中Pd(II)周围的配位几何形状接近方平面，配体呈反式关系。
Molecular and Crystal Structure of trans-(Dicyanato)-bis(triphenylphosphine)palladium(II)
The triphenylphosphine (PPh3) displaces the acetonitrile from [PdCl2(CH3CN)2], and subsequent addition of the potassium cyanate causes substitution of the chloro ligand by NCO- to yield trans-[Pd(NCO)2(PPh3)2]. The complex was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The title compound was crystallized in a triclinic system, space group P1 with a = 9.213(3)A, b = 9.781(7)A, c = 10.483(5)A, α = 111.39(5)°, β = 93.49(3)°, γ = 103.81(4)°, V = 845.0(1)A3, Z = 1. The coordination geometry around Pd(II) in this complex is nearly square-planar, with the ligands in a trans relationship.
