摘要
合成了萘啶酮的单核和双核银配合物Ag2(L1)2(HL1=5,7-二甲基-1,8-萘啶-2-酮)(1)和[Ag(HL2)(PPh3)2]·2H2O(H2L2=1,8-萘啶-2,7-二酮)(2)。并通过元素分析,红外光谱及X-射线单晶衍射对其进行了结构表征。配合物1的晶体属单斜晶系,P1空间群。中心金属银为三配位T型几何构型,Ag-Ag间距离为0.2748(2)nm,具有强的Ag…Ag作用。配合物2的晶体属三斜晶系,P21/n空间群。银与1个氮原子及2个磷原子形成三配位结构。
Complex Ag2(L1)2 (HL1=5,7-dimethyl- 1,8-naphthyridin-2-one) (1) and [Ag(HL2)(PPh3)2]· 2H2O (H2L2= 1,8- naphthyridin-2,7-dione) (2) have been prepared and their structures were determined by X-ray diffraction. Ag2(L1)2 crystallizes in a monoclinic space P1. The Ag^+ ion features a T-shaped tricoordinated geometry, being coordinated by two nitrogen atoms from two different L1 ligands and one from Ag... Ag interaction. The Ag... Ag bond distance is 0.274 8(2) nm showing some metallophilic interaction. [Ag(HL2)(PPh3)2] ·2H2O crystallizes in a triclinic space group P21/n. The Ag^+ ion is tricoordinated by one N atom from L2 and two triphenylphosphine. CCDC: 608043, 1; 608044, 2.
