[Pt(SeC5H4N)2(dppp)}MX2] (M = Cd, Hg, Cu; X = Cl, OAc). Whereas, reaction with Zn(OAc)2, on extraction with dichloromethane resulted the product with the loss of one selenium atom of composition [Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2]. These complexes were characterized by elemental analyses and NMR (1H, 31P, 77Se, 195Pt) spectroscopy. The molecular structure of [Pt(C5H4N)(SeC5H4N)(dppp)}ZnCl2] was established by single
的反应[PT(秒5 ħ 4 N)2(P∩P)]与M(OAC)2 ·2H 2 O / MX 2(P∩P= DPPM,DPPP; M =锌,镉,汞,铜; X = Cl)生成的各种产物取决于膦的性质。在dppm的情况下,[Pt(SeC 5 H 4 N)2(dppm)]与M(OAc)2 .2H 2 O / MX 2(M = Zn,Cd,Hg)之间的反应提供组成为[ PtCl 2(dppm)]。类似地,与“ dppp”类似物的反应产生加合物[Pt(SeC 5 H 4 N)2(dppp)} MX 2](M = Cd,Hg,Cu; X = Cl,OAc)。然而,用Zn(OAc)反应2,用二氯甲烷萃取得到与组合物中一种硒原子[的Pt(C损失的产品5 ħ 4 N)(秒5 ħ 4 N)(DPPP)}的ZnCl 2 ] 。这些配合物通过元素分析和NMR(1 H,31 P,77 Se,195 Pt)光谱进行表
