A new tetranuclear silver(I) complex with the formula of [Ag_4(MMPzA)_2(dmPz)_4(H_2DPC)_2](H_2O)_4(1, MMPz A = mono(3,5-bimethyl-pyrazolmethyl)amine), dm Pz = 3,5-dimethylpyrazole, H_2DPC = pyridine-3,4-dicarboxylic acid) has been synthesized and characterized by single-crystal X-ray diffraction method. The title complex crystallizes in the triclinic system, space group P1 with a = 10.5532(13), b = 11.5071(18), c = 13.3951(17) ?, α = 97.3190(10), β = 106.7360(10), γ = 108.0770(10)o, V = 1438.3(3) ?3, Z = 1, Dc = 1.691 g/cm3, F(000) = 736, μ = 1.421 mm-1, the final R = 0.0400 and w R = 0.0942 for 5097 observed reflections(I > 2σ(I)). The intermolecular hydrogen bonding interaction extends the complex into a 1D chain structure. In addition, the complex was tested in vitro for its antibacterial activity and it exhibited significant activity, especially against penicillium.
