The molecular structure was determined by single-crystal X-ray analysis. The compound crystallizes in the monoclinic system, space group P2_1/n with a = 12.2156, b = 13.5696, c = 22.5602 A, β = 90.061o, Z = 4 and V = 3739.6(3)A^3. The new 1D binuclear coordination polymer {[bis(py-κN)bis(3,5-dinitrosal κ-O,O′) Zn(Ⅱ)][bis(py-κN)Zn(Ⅱ)]} resulted from two different types of moieties. The polymer [bis(py-κN)bis(3,5-dinitrosal κ-O,O′)Zn(Ⅱ)] unit is connected with [bis(py-κN) Zn(Ⅱ)] by zigzag topology. One zinc(Ⅱ) cation has a six-fold coordination environment, in which the metal atom is connected with four oxygen atoms of two 3,5-dinitrosalicylic acids to form equatorial bonds and two nitrogen atoms of pyridine to generate the axial bonds. Other four-fold nucleus contain two Zn-O bonds from different 3,5-dinitrosalicylic acids and two bonds with the Natom of pyridine. Antimicrobial assay results indicated that the compound showed moderate activities against different bacterial and fungal strains.展开更多
