[P(CHCOCH2R)O(OEt)2]–[R = NEt2(L2), [graphic omitted]H2(L3), or [graphic omitted]H2(L4)] form five-co-ordinate complexes [MX(L)](M = CoII, L = L2, L3, or L4 and X = Br, I, NCS, or NCSe; M = ZnII, L = L3 of L4, and X = Cl, Br, or I). A trigonal-bipyramidal stereochemistry is ascribed to these complexes, essentially on the basis of electronic and vibrational spectra and of X-ray powder and single-crystal results
阴离子[P(CHCOCH 2 R)O(OEt)2 ] – [R = NEt 2(L 2),[省略图] H 2(L 3)或[省略图] H 2(L 4) ]形式五坐标复合物[MX(L)](M = Co II,L = L 2,L 3或L 4且X = Br,I,
NCS或
NCSe; M = Zn II,L = L 3 L 4的基团,并且X = Cl,Br或I)。基本上基于电子光谱和振动光谱以及X的光谱,将三角双锥型立体
化学归因于这些络合物-射线粉末和单晶结果。可以通过使用X,
