Bis(5-bromo-pyridine-2-carboxyl-ato-?O)triphenyl-anti-mony(V).

ABSTRACT: In the title compound, [Sb(C(6)H(5))(3)(C(6)H(3)BrNO(2))(2)], the Sb center has a distorted trigonal-bipyramidal geometry, with two carboxyl-ate O atoms of two 5-bromo-pyridine-2-carboxyl-ate ligands in equatorial positions and three phenyl ligands in axial positions. The crystal structure is stabilized by C-H?Br hydrogen bonds and inter-molecular C-Br?? inter-actions [C?? = 3.57?(1)?Å].

Project description:The title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-gen donor and extends two 5-bromo-pyridine-3-carboxyl-ate groups to bridge to adjacent binuclear sites in the bc plane. Each cage is linked to four adjacent cages in the plane. The intra-dimer Cu?Cu distance is 2.6465?(5)?Å. The remaining 5-bromo-pyridine-3-carboxyl-ate groups project into the inter-lamellar domain and inter-digitate in pairs from each neighboring layer.
