N2 - A series of mononuclear, dinuclear and polynuclear silver(I) complexes (1-6) bearing 2-pyrazole-substituted 1,10-phenanthroline derivatives (L 1, FL1, L2) have been synthesized and characterized by 1H and 13C NMR, IR spectroscopy, elemental analysis, and single crystal X-ray diffraction. Reaction of L 1 (L1 = 2-(3,5-dimethylpyrazol-1-yl)-1,10-phenanthroline) with AgClO4 or AgBF4 afforded two dinuclear silver(I) complexes [Ag2(L1)2(CH3CN) 2](ClO4)2 (1) and [Ag2(L 1)2(CH3CN)2](BF4) 2 (2), in which two [AgL1(CH3CN)]+ units are linked by Ag⋯Ag interaction (Ag⋯Ag separation: 3.208(2) and 3.248(1) Å, respectively). A one-dimensional polymer {[AgL 1](BF4)}∞ (3) consisting of an infinite⋯Ag⋯Ag⋯Ag⋯chain (Ag⋯Ag separation: 3.059(1) Å), as well as a dinuclear complex [Ag2(ClO 4)2(L1)2] (4) in which the perchlorate anions instead of solvents are involved in the metal coordination, have also been obtained. The mononuclear complex [Ag(FL 1)2](BF4) (5) was synthesized from FL1 (FL1 = 2-(3,5- bis(trifluoromethyl)pyrazol-1-yl)-1,10-phenanthroline) and AgBF4, while the dinuclear [Ag2(BF4)2(L 2)2] (6) was isolated from L2 (L2 = 2-[N-(3-methyl-5-phenylpyrazole)]-1,10-phenanthroline). The photoluminescence properties of the ligands and complexes 1-6 have been studied both in the solid state and in solution.
