Diaqua-dichloridomethyl-phenyl-tin(IV)-1,4,7,10,13-penta-oxacyclo-penta-decane (1/1).

ABSTRACT: The asymmetric unit of the title cocrystal, [Sn(CH(3))(C(6)H(5))Cl(2)(H(2)O)(2)]·C(10)H(20)O(5), contains two independent for-mula units. The organotin molecules exhibit a six-coordinate metal atom and are linked to the crown ether molecules by water-crown ether O-H⋯O hydrogen bonds into a linear chain running along [101]. Each coordinated water mol-ecule forms a pair of hydrogen bonds to the same crown ether; for the crown ether mol-ecules, only four of the five O atoms are engaged in hydrogen-bonding inter-actions. The metal ions show a distorted trans-C(2)SnCl(2)O(2) octa-hedral coordination geometry [C-Sn-C = 175.3 (1) and 178.9 (1)°].

Di-?-chlorido-bis-[aqua-chloridodimethyl-tin(IV)]-1,4,7,10,13-penta-oxacyclo-penta-decane (1/1).

Project description:The Sn, Cl and water O atoms of the title compound, [Sn(2)(CH(3))(4)Cl(4)(H(2)O)(2)]·C(10)H(20)O(5), lie on a special position of 2 site symmetry. The Sn(IV) atom shows cis-C(2)SnCl(2)O trigonal-bipyramidal coordination [C-Sn-C = 157.0?(1)°]; however, two [Me(2)SnCl(2)(H(2)O)] units are linked by a tin-chlorine bridge [Sn?Cl = 3.247?(1)?Å] across a center of inversion, generating a dinuclear species, so that the geometry is better regarded as a mer-C(2)SnCl(3)O octa-hedron. The crown ether inter-acts through O-H?O hydrogen with the metal atom through the coordinated water mol-ecules in an outer-sphere manner, generating a hydrogen-bonded chain running along [101]. The 15-crown-5 mol-ecule is disordered over the 2/m site.

Diaqua-(1,4,7,10,13-penta-oxacyclo-penta-deca-ne)iron(II) bis-(μ-cis-1,2-dicyano-1,2-ethyl-enedithiol-ato)bis-[(cis-1,2-dicyano-1,2-ethyl-enedithiol-ato)ferrate(III)] 1,4,7,10,13-penta-oxacyclo-penta-decane disolvate.

Project description:The title compound, [Fe(C(10)H(20)O(5))(H(2)O)(2)][Fe(2)(C(4)N(2)S(2))(4)]·2C(10)H(20)O(5), consists of an [Fe(II)(15-crown-5)(H(2)O)(2)](2+) cation, sandwiched between and O-H⋯O hydrogen bonded by two additional 15-crown-5 ether mol-ecules and two independent [Fe(III)(mnt)(2)](-) anions, where 15-crown-5 ether denotes 1,4,7,10,13-penta-oxacyclo-penta-decane and mnt denotes cis-1,2-dicyano-1,2-ethyl-enedithiol-ate. Each independent [Fe(III)(mnt)(2)](-) unit forms a centrosymmetric dimer supported by two inter-monomer Fe(III)-S bonds [Fe-S = 2.4715 (9) and 2.4452 (9) Å]. In the crystal structure, the dimers form one-dimensional π-π stacks along the a axis, with an inter-planar separation of 3.38 (6) Å.

fac-Aqua-(2-carboxy-ethyl-?C,O)trichlorido-tin(IV)-1,4,7,10,13-penta-oxacyclo-penta-deca-ne-water (1/1/2).

Project description:In the title compound, [Sn(C(3)H(5)O(2))Cl(3)(H(2)O)]·C(10)H(20)O(5)·2H(2)O, the Sn(IV) atom is octa-hedrally coordinated within a fac-CO(2)Cl(3) donor set, arising from the C,O-bidentate carboxy-ethyl ligand, a water mol-ecule and three chloride ligands. In the crystal, supra-molecular chains linked by O-H?O hydrogen bonds propagate along the c axis These chains are connected into layers in the ac plane via C-H?O inter-actions.

fac-(2-Amido-ethyl-?C,O)aqua-tri-chlorido-tin(IV) 1,4,7,10,13,16-hexa-oxacyclo-octa-decane (2/1).

Project description:The asymmetric unit of the title compound, [Sn(C(3)H(6)NO)Cl(3)(H(2)O)](2)·C(12)H(24)O(6), comprises a six-coordinate tin complex and a 18-crown-6 mol-ecule, the latter disposed about a centre of inversion. The tin atom is coordinated by three Cl atoms, that define a facial arrangement, a chelating C-,O- ligand, and a water mol-ecule. The resulting CCl(3)O(2) donor set defines a distorted octa-hedral geometry. The tin-bound aqua ligand forms O-H?O hydrogen bonds to the centrosymmetric 18-crown-6 mol-ecule, resulting in a tri-mol-ecular aggregate. These assemble into a supra-molecular chain along the a axis being connected by N-H?O hydrogen bonds.

Poly[diaqua-(?(4)-carboxyl-atomethyl-phospho-nato)(?(4)-carb-oxy-methyl-phospho-nato)penta-deca-methyl-penta-tin(IV)].

Project description:The central Sn(IV) atom of the penta-nuclear title complex, {[Sn(CH(3))(3)](3)O(2)C(CH(2))PO(3)[Sn(CH(3))(3)(H(2)O)](2)HO(2)C(CH(2))PO(3)}, is located on a twofold rotation axis; due to symmetry, the H atom of the carboxyl group of the anion is disordered with a site occupancy of 0.5. The central Sn(IV) atom is bonded to three methyl groups (one of which is disordered about the twofold rotation axis) and is symmetrically trans coordinated by two phospho-nate groups with Sn-O = 2.2665?(12)?Å while the other SnMe(3) residues are asymmetrically trans coordinated with Sn-O = 2.1587?(12) and 2.3756?(13)?Å for one residue and Sn-O = 2.1522?(12) and 2.4335?(12)?Å for the other; the Sn-O distances involving two O atoms trans to carboxyl-ate are longer than those trans to phospho-nate groups. The Sn-C distances lie in a very narrow range [2.112?(2)-2.133?(3)?Å]. The oxyanion behaves as a tetra-coordinating ligand. The bridging mode of the latter leads to the formation of layers parallel to (001) that are inter-connected by O-H?O and C-H?O hydrogen bonds.
