چکیده
In the title complex, [Sb(C(6)H(5))(3)(C(6)H(3)ClNO(2))Cl], the Sb center has a close to ideal trigonal-bipyramidal geometry, with the phenyl ligands in equatorial positions and the chloride and a carboxyl-ate O atom in axial positions. Weak C-H⋯O contacts generate dimeric units via crystallographic inversion centres.

μ-Oxido-bis[(2-chloronicotinato-κO)triphenylantimony(V)]
A new dinuclear triphenyl-anti-mony(V) derivative with an oxide bridge, [Sb(2)(C(6)H(5))(6)(C(6)H(3)ClNO(2))(2)O], has been synthesized. Each Sb atom is five-coordianted by three C atoms and two O atoms in a distorted trigonal-bipyramidal geometry. Metal centers are bridged by a μ(2)-oxide functionality, and phenyl substituents on Sb atoms are in an staggered arrangement. The Sb-O-Sb bridge dis...

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].
متن کاملBis(2-amino-4-chlorobenzoato)triphenylantimony(V)
The title complex mol-ecule, [Sb(C(6)H(5))(3)(C(7)H(5)ClNO(2))(2)], possesses crystallographically imposed C(2) symmetry. The Sb atom exhibits a trigonal-bipyramidal geometry with the axial positions occupied by the O atoms of two carboxyl-ate groups and the equatorial positions by the C atoms of the phenyl groups. Intra-molecular N-H⋯O and C-H⋯O hydrogen bonds occur.
