چکیده
In the title mol-ecule, [Sn(C(7)H(6)Cl)(2)(C(6)H(4)NO(2))(2)(H(2)O)], the O atoms of the two chelating nicotinate groups and the O atom of the coordinated water mol-ecule comprise the penta-gonal plane of the trans-C(2)SnO(5) penta-gonal-bipyramid [C-Sn-C = 178.62 (11) °] surrounding the Sn(IV) atom. In the crystal, adjacent mol-ecules are linked by O-H⋯N hydrogen bonds, generating a chain running along the body diagonal of the triclinic unit cell.

Two nicotinate binding modes are observed in the dinuclear title compound, [Sn(2)(C(7)H(6)Br)(4)(C(6)H(4)NO(2))(4)(H(2)O)(2)]: in the first, a terminal O,O'-chelating molecule binds to a water-coordinated diorganotin cation, while the second mode corresponds to an O:N-bridging molecule which binds to two cations. The two Sn atoms exist in trans-C(2)SnNO(4) penta-gonal-bipyramidal geometries. Ad...

The dinuclear title complex, [Sn(2)(C(7)H(6)Cl)(4)(C(9)H(16)NO(2)S(2))(4)], lies on a center of inversion. The Sn(IV) atoms are chelated by one of the two carboxyl-ate ions; the other carboxyl-ate ion bridges two metal atoms. The geometry of the six-coordinate Sn(IV) atom is a distorted trans-C(2)SnO(4) octa-hedron [C-Sn-C = 155.32 (8)°].

The Sn(IV) atom in the three independent mol-ecules of the title compound, [Sn(C(7)H(6)Cl)(2)(C(9)H(6)NO)Cl], is N,O-chelated by the quinolin-8-olate anion and exists in a cis-C(2)SnNOCl trigonal-bipyramidal geometry; the O atom of the anion and the two benzyl C atoms lie in the equatorial plane.

The title compound, [Sn(2)(C(6)H(5))(6)(C(8)H(5)NO(4))], contains two triphenyl-tin groups bridged by a 2-amino-terephthalate ligand. The two Sn(IV) centers have similar distorted tetra-hedral coordination geometries. Each Sn(IV) atom is bonded to three phenyl C atoms and one O atom from a carboxyl-ate group. The other O atom of the carboxyl-ate group has a weak inter-action with the Sn atom. T...

The asymmetric unit of the title compound, [Sn(4)(C(7)H(6)Cl)(8)(C(8)H(7)O(2))(2)O(2)(OH)(2)], comprises one-half of the centrosymmetric tin(IV) complex. μ(3)-Oxide and μ(2)-hydroxide bridges link the four five-coordinate Sn(IV) atoms to generate three fused four-membered Sn-O-Sn-O rings in a ladder-like structure. The two endocyclic Sn atoms each bind to two μ(3)-oxide anions and a μ(2)-hydrox...
