摘要:二膦ph 2 P [ch 2] N Pph 2(n = 1-4)形成化学计量学的ir I的新型反式羰基络合物[{ir(co)cl(diphosphine)} M],其中二膦(n = 1,3或4)桥接金属原子.与先前的假设相反,Ph 2 P [ch 2] 2 Pph 2的络合物为[ir(co){ph 2 P(ch 2)2 Pph 2 } 2] [ir(co)2 Cl 2].钯的二膦配合物ii和pt Ii,其中一些是首次描述,均为顺式几何.在每种情况下,Ph 2 P [ch 2] 2 Pph 2螯合金属,并且该络合物是单核的,但是ph 2 P [ch 2] 4 Pph 2桥接三核络合物的金属原子.二膦ph 2 P [ch 2] 3 Pph 2螯合了pd Ii,但形成了pt Ii的桥联络合物.当将由螯合配体对向的角度pmp超过90°时,将发生由二膦配体的桥接.
