The syntheses and structural characterizations of two novel 2-bromobenzoatozinc(II) complexes-[Zn(2-BrC6H4COO)(2)](n) (I) and [Zn(2-BrC6H4COO)(2)(mnad)](2) (II), where mnad is N-methylnicotinamide are reported. Compound (I) crystallized with a monoclinic lattice (space group P2(1)/c) and is polymeric in solid state. Its cell parameters are: a = 7.37220(10) angstrom, b = 19.9639(3) angstrom, c = 30.2756(5) angstrom, beta = 94.7510(7)degrees, V = 4440.59(12) angstrom(3), Z = 4. The coordination environments of all zinc atoms are distorted tetrahedra built from four carboxylate oxygen atoms coming from four 2-bromobenzoato ligands. Compound (II) crystallized with a monoclinic lattice (space group P2(1)/c) with a = 11.7488(2) angstrom, b = 20.3683(3) angstrom, c = 9.30130(10) angstrom, beta = 100.3941(11)degrees, V = 2189.30(5) angstrom(3), Z = 2. This dimeric molecule features a paddle-wheel [Zn2O8] cage in solid state; the coordination environment of the central atom is square pyramidal consisting of four carboxylate oxygen atoms and the pyridine N atom of the mnad ligand.
