title: A novel three-dimensional copper(I) coordination polymer constructed from a copper-bromide net and nicotinic acid ligands.
abstract: The title compound, poly[mu(3)-bromido-(pyridine-3-carboxylato-kappaN)copper(I)], [CuBr(C(6)H(5)NO(2))](n), is a novel coordination polymer based on a copper-bromide net and nicotinic acid ligands. The asymmetric unit contains one copper(I) ion, one bromide ligand and one nicotinic acid ligand, all on general positions. The Cu(I) atom is tetrahedral and coordinated by three bridging Br atoms and the N atom from the nicotinic acid ligand. The Cu-Br units form alternating six-membered chair-patterned rings in net-like layers. The attached nicotinic acid units point alternately up and down. The layers are assembled into a three-dimensional network via intermolecular O-H...O and C-H...Br hydrogen-bonding interactions.
