crystallography (for compounds 1, 2 and 8). The geometry about each metal centre is distorted square planar with trans bond angles of: compound 1, P–Pt–S, 170.31(11), 173.18(10)°; compound 2, P–Pt–S, 168.97(5), 171.43(5)°; compound 8, P–Pd–S, 170.78(8), 171.83(8)°. The bite angles P(1)–M–P(2) and angles trans to bite angles, S(1)–M–S(2), are, respectively: compound 1, 85.68(11), 82.69(11)°; compound 2, 86.65(5)
摘要由四氯化铂与吡啶-2-硫酮(C5H5NS)在Et3N碱存在下反应制得了一系列化学计量为顺式[Pt(η1-S-C5H4NS)2(LL)]的铂(II)配合物。在乙醇-苯混合物中,然后添加双(叔膦),即。Ph2P–X–PPh2}或磷化硫族化物Ph2P–CH2–P(E)Ph2} X(LL)=(CH2)2(dppe)(1),CHCH(dppen)(2),( CH 2)3(dppp)(3),(CH 2)4(dppb)(4),E = S,dppmPS(5),E = Se,dppmPSe(6)}。钯(II)配合物,即。制备[Pd(η1-S-C5H4NS)2(LL)] LL = dppm(X = CH2)(7),dppe(8),dppp(9),dppmPS(10),dppmPSe(11)}通过在NaOH水溶液中使悬浮在乙醇中的[PdCl2(diphosphines)]与C5H5NS反应。所有这
