合成了两个异亚硝基乙酰丙酮亚胺Pd(II)配合物,Pd(o-BrC_6H_4-IAI)_2 (1) 和Pd(C_6H_5CH_2-IAI)_2 (2)(IAI = isonitrosoacetylacetoneimino),用IR和 Raman光谱对两个配合物进行了表征,并测定了配合物1的晶体结构。配合物1晶体 属单斜晶系,空间群为P2_1/c,晶胞参数:a = 0.8013(2) nm,b = 1.8775(4) nm,c = 0.7905(2) nm,β = 98.22(3)°,V = 1.1770(5) nm~3,Z = 2,D_c = 1.892 g·cm~(-3),F(000) = 656,R = 0.0663。在这两个配合物中,二齿 Schiff碱配体的异亚硝基(肟基)的N原子和亚胺的N原子与Pd(II)配位,形成反式 的PdN_4平面正方形配位构型。

Two palladium complexes of isonitrosoacetylacetoneimine, Pd(o- BrC_6H_4-IAI)_2 (1) and Pd(C_6H_5CH_2-IAI)_2 (2), were synthesized and characterized by IR and Raman spectra. Complex 1 crystallizes in monoclinic system, space group P2_1/c, with parameters: a = 0.8013(2) nm, b = 1.8775(4) nm, c = 0.7905(2) nm, β = 98.22(3)°, V = 1.1770(5) nm~3, Z = 2, D_c = 1.892 g·cm~(-3)and F(000) = 656. The final R value is 0.0663 for 1742 observed reflections with I ≥ 2σ(I). The Pd (II) atoms have trans distorted square-planar PdN_4 coordination composed of imino-nitrogen atoms and oximo-nitrogen atoms from the two Schiff base ligands.
