Bis(µ-3,5-difluorobenzoato)bis[(3,5-di-fluorobenzoato)dimethyltin(IV)].

In the dinuclear title complex, [Sn(2)(CH(3))(4)(C(7)H(3)F(2)O(2))(4)], the Sn(IV) atom is chelated by two 3,5-difluoro-benzoate (dfb) anions and coordinated by two methyl groups while an O atom from the adjacent dfb anion bridges the Sb atom with a longer Sb-O bond distance of 2.793 (4) Å. The complex mol-ecule has 2 symmetry and the Sn(IV) atom is in a distorted penta-gonal-bipyramidal coordination geometry. In the crystal, mol-ecules are connected by C-H⋯O and C-H⋯F hydrogen bonds.

Dichloridoocta-kis(2-chloro-benz-yl)di-µ(2)-hydroxido-di-µ(3)-oxido-tetra-tin(IV).

The title tetra-nuclear Sn(IV) compound, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)], has site symmetry . Two O(2-) and two OH(-) anions bridge four Sn(IV) cations to form the tetra-nuclear compound. The two independent Sn(IV) cations assume SnO(3)C(2) and SnO(2)C(2)Cl distorted trigonal-bipyramidal coordination geometries. Intra-molecular O-H⋯Cl hydrogen bonding is present in the structure. One Cl atom of a chloro-benzyl ligand is disordered over two sites with an occupancy ratio of 0.693 (2):0.307 (2).

Dimethano-lbis[N'-(3-pyridylmethyl-ene)benzohydrazide]sodium(I) iodide.

The molecule of the title compound, [Na(C(13)H(11)N(3)O)(2)(CH(3)OH)(2)]I, is non-planar, with the Na atom chelated by the O atoms and the N atoms of two N'-(3-pyridylmethyl-ene)benzohydrazide ligands and both O atoms of two methanol ligands. The asymmetric unit consists of one half-mol-ecule. The Na atom is located on a crystallographic centre of inversion. The six-coordinate Na atom adopts a distorted octa-hedral coordination. In the crystal structure, inter-molecular N-H⋯I and O-H⋯N hydrogen bonds link the mol-ecules into a two-dimensional network.
