配合物Pt_2(CN)_4(μ-dppm)_2(其中dppm=(Ph_2P)_2CH_2),Mr=1335.10;空间群P2_1/c;α=13.129(3),b=15.065(6),c=14.630(4);β=106.47(2)°;V=2775(2)~3;Dc=1.60g/cm^(-1);Z=2;λ(MoK_x)=0.71069;F(000)=1304;μ(MoK_α)=52.46cm^(-1);最后的R=0.051。其中dppm以桥连方式与金属配位,形成一个八元环的骨架结构。

In this paper, the synthesis, crystal structure of Pt2(μ-dppm)2 (CN)4, (dppm =Ph2PCH2PPh2), were reported. The complex is monoclinic system, space group is P21/c with cell parameters a=13.129(3), b=15.065(6), c=14.630(4)A; β= 106.47(2)°; V=2775(2) A3; z=2; Dc=1.60g/cm3; λ(MoKα)=0.71069A;F(000)=1304; μ(MoKα)=52.46cm-1. The final R factor is R=0.051. An eight-membered ring exists in this complex owing to two dppm bridge both platinum atoms.
