چکیده
In the title compound, [Sb(C(6)H(5))(3)(C(7)H(5)ClNO(2))(2)], the Sb center has a distorted trigonal-bipyramidal geometry, with the O atoms of two carboxyl-ate groups in axial positions and the C atoms of the phenyl groups in equatorial positions. Intra-molecular C-H⋯O inter-actions occur. The mol-ecules are connected by inter-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen-bonding inter-actions and C-H⋯π stacking inter-actions, forming a three-dimensional supra-molecular framework.
