Two binuclear silver complexes, [Ag2{μ-S2P(OCH2Ph)2}2(phen)2] (1) and [Ag2{μ- SEP(OCH2CH2Ph)2}E(phen)2] (2), were synthesized and characterized by elemental analysis, infrared spectrum, thermo-gravimetri...Two binuclear silver complexes, [Ag2{μ-S2P(OCH2Ph)2}2(phen)2] (1) and [Ag2{μ- SEP(OCH2CH2Ph)2}E(phen)2] (2), were synthesized and characterized by elemental analysis, infrared spectrum, thermo-gravimetric analysis and X-ray single-crystal diffraction. Complex 1 crystallizes in the triclinic system, space group P1 with a = 9.7881(4), b = 10.7726(4), c = 13.1952(6) A, a = 103.686(4), ,8= 99.477(3), ), = 107.494(4)°, F= 1246.88(9)A3, Dc = 1.591 g.m-3 and Z = 1; Complex 2 is of monoclinic system, space group P2jn with a = 10.6014(8), b = 24.3969(15), c = 11.5353(10)A,β= 14.125(10)°, F= 2722.9(4) A3, Dc = 1.526 g.m-3 and Z = 2. In the molecules of 1 and 2, O,O'-dialkyldithiophosphate anions, (PhCHEO)PS2 and (PhCH2CHEO)PS2 act as bridging ligands and connect two Ag(I) centers into a binuclear unit with AgES4P2 eight-membered rings in "chair" conformations. In both crystal structures, face-to-face π-π stacking interactions between the adjacent paralleling aromatic rings of 1,10-phenanthroline play a prominent role in the crystal packing and result in a 1D chain.
