A one-dimensional zinc-containing coordination polymer, [Zn2(NBA)2(4,4--bipy)]n (NBA = 3-nitrobenzoic acid, 4,4--bipy = 4,4--bipyrindine), has been solvothermally synthesized and characterized by single-crystal X-ray diffraction, IR and elemental analysis.The crystal structure is of monoclinic, space group C2/c with a = 24.6478(2), b = 14.0964(3), c = 11.4275(2) -, β =108.7870(10)°, V = 3758.89(11) -3, C38H20N6O16Zn2, Mr = 947.34, Z = 4, Dc = 1.674 g/cm3, μ = 1.363 mm-1, F(000) = 1912, R = 0.0720 and wR = 0.2277 for 2841 observed reflections (I > 2((I)).In this compound, NBA in syn-syn coordination mode bridges zinc centers into dimeric- zinctetracarboxylate [Zn2(COO)4] secondary building units (SBUs) which are linked through μ-4,4--bpy affording 1D alternating chains.These adjacent chains are further stacked through intermolecular π…π interactions to form a 3D framework.
