【Abstract】 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.更多还原
