چکیده
In the title co-crystal, [Sn(4)(CH(3))(8)Cl(4)O(2)]·2[Sn(CH(3))(2)Cl(C(4)H(8)NS(2))], all the Sn(IV) atoms are in distorted trigonal-bipyramidal environments. In the mononuclear species, the carbodithio-ate ligand is unsymmetrically coordinated to the Sn(IV) atom, with Sn-S distances of 2.6722 (12) and 2.4706 (11) Å. All atoms with the exception of the methyl groups and one of the pyrrolidine ring CH(2) groups lie on a crystallographic mirror plane. The pyrrolidine ring exhibits an envelope conformation; the C atom at the flap is disordered above and below the plane of symmetry with fixed occupation factors of 0.50. The centrosymmetric dimer species consists of a central Sn(2)O(2) unit with two adjacent Sn(2)OCl four-membered rings.

In the title compound, [Sn(4)(CH(3))(8)(C(8)H(9)O(2))(2)Cl(2)O(2)], the tetra-nuclear complex mol-ecule has crystallographically imposed inversion symmetry. The coordination polyhedron about the two central Sn atoms is distorted trigonal-bipyramidal, whilst the two peripheral metal atoms bonded to the carboxyl-ate groups have a distorted octa-hedral coordination geometry. In the crystal, mol-ec...

The tetra-nuclear title compound, [Sn4(CH3)8(C3H7O)2O2(C3H4N3S)2], lies about a center of inversion; the mol-ecule features a three-rung-staircase Sn4O4 core in which two Sn(IV) atoms are bridged by the 4-methyl-5-sulfanyl-idene-4,5-dihydro-1H-1,2,4-triazol-1-ide group. The negatively charged N atom of the group binds to the terminal Sn(IV) atom at a shorter distance [Sn-N = 2.236 (2) Å] compar...

The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-...

The title compound, [Sn(4)(C(4)H(9))(8)(C(15)H(12)NO(3))(2)(CH(3)O)(2)O(2)], is a centrosymmetric dimer and displays a ladder type structural motif. There are four Sn(IV) centres which can be divided into two sorts, viz. two endocyclic and two exocyclic. The endo- and exocyclic Sn(IV) centres are linked by bidentate deprotonated methanol and μ(3)-O atoms. Each exocyclic Sn(IV) centre is also co...
