(4-Chloro-3-nitro-benzoato)triphenyl-tin(IV).

ABSTRACT: In the title compound, [Sn(C(6)H(5))(3)(C(7)H(3)ClNO(4))], the four-coordinate Sn(IV) atom exists in a distorted tetra-hedral geometry, formed by a monodentate carboxyl-ate group and three phenyl rings. The conformation is stabilized by an intra-molecular C-H?O hydrogen bond, which generates an S(5) ring. The aromatic ring of the 4-chloro-3-nitro-benzoate ligand makes dihedral angles of 75.64?(12), 64.37?(12) and 2.97?(12)° with the three phenyl ligands. The O atoms of the nitro group are disordered over two sets of sites in a 0.817?(5):0.183?(5) ratio. In the crystal, mol-ecules are linked via inter-molecular C-H?O hydrogen bonds into chains running parallel to [010].

Project description:The title complex, [Sn(4)(C(4)H(9))(8)(C(7)H(3)ClNO(4))(4)O(2)], is a cluster formed by a crystallographic inversion center around the central Sn(2)O(2) ring. Both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. The O atoms of the bridging benzoate anion are disordered over two sites with an occupancy ratio of 0.862?(12):0.138?(12). One of the butyl groups coordinated to the Sn(2)O(2) ring is disordered over two sites with an occupancy ratio of 0.780?(8):0.220?(8), whereas both of the two butyl groups coordinated to the other Sn atom are disordered over two sites with occupancy ratios of 0.788?(5):0.212?(5) and 0.827?(10):0.173?(10). All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. In the crystal, complex mol-ecules are stacked down [010] with weak inter-molecular C-H?? inter-actions stabilizing the crystal structure.
