The title complex [HSr_3(pda)_3(H_2O)_3Cl]n(1, H_2pda = pyridine-2,6-dicarboxylic acid) has been prepared under two-step solvothermal conditions. It has been characterized by X-ray single-crystal diffraction, IR, TGA-DSC and elemental analysis. The crystal belongs to the trigonal system, space group R-3 with a = 14.484(2), b = 14.484(2), c = 21.970(4) ?, γ = 120 o, V = 3991.4(11) ?~3, C_(21)H_(16)ClN_3O(1)_5Sr_3, M_r = 848.68, Z = 6, Dc = 2.118 g/cm~3, μ = 6.175 mm~(-1), F(000) = 2484, the final R = 0.0457 and w R = 0.1139. This complex possesses a 3-D structure constructed from [HSr_3(pda)_3(H_2O)_3Cl]_2 units and connected by coordinated carboxylate groups of pda2-ligands. The topology symbol of this network is(4~(12)6~3). Luminescent property of the title complex has been investigated at room temperature.
