چکیده
In the the title compound, C(6)H(5)BrN(2)O, an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring. In the crystal structure, inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds link the mol-ecules, leading to sheets propagating in (100).

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⋯π inter-actions [C⋯π = 3.57 (1) Å].

In the title dinuclear compound, [Zn(2)(C(6)H(6)N(3)O)(2)(C(6)H(7)N(3)O)(2)](NO(3))(2), the Zn(II) cation is N,N'-chelated by one pyridine-2-carboxamide oximate anion and one pyridine-2-carboxamide oxime mol-ecule, and is further bridged by an oxime O atom from the adjacent pyridine-2-carboxamide oximate anion, forming a distorted trigonal bipyramidal coordination. Two pyridine-2-carboxamide ox...

The carboxylic acid residue in the title compound, C(6)H(4)BrNO(2), is twisted out of the plane of the other atoms, as indicated by the (Br)C-C-C-O(carbon-yl) torsion angle of -20.1 (9)°. In the crystal, supra-molecular chains mediated by O-H⋯N hydrogen bonds are formed with base vector [201] and C-H⋯O inter-actions reinforce the packing.

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-...
