Hexa-kis-(dimethyl sulfoxide-?O)zinc(II) poly-iodide.

ABSTRACT: The title compound, [Zn{(CH3)2SO}6]I4, is a one-dimensional supra-molecular polymer along a threefold rotation axis of the space group. It is built up from discrete [Zn{(CH3)2SO}6](2+) units connected through non-classical hydrogen bonds to linear I4 (2-) polyiodide anions (C-H?I = 3.168?Å). The Zn(II) ion in the cation has an octa-hedral coordination geometry, with all six Zn-O bond lengths being equivalent, at 2.111?(4)?Å. The linear polyiodide anion contains a neutral I2 mol-ecule weakly coordinated to two iodide ions.

Project description:The title salt, [Mn(C2H6OS)6]I4, is made up from discrete [Mn(DMSO)6]2+ (DMSO is dimethyl sulfoxide) units connected through non-classical hydrogen bonds to linear I42- tetra-iodide anions. The MnII ion in the cation, situated on a position with site symmetry -3., is octa-hedrally coordinated by O atoms of the DMSO mol-ecule with an Mn-O distance of 2.1808?(12)?Å. The I42- anion contains a neutral I2 mol-ecule weakly coordinated by two iodide ions, forming a linear centrosymmetric tetra-iodide anion. The title compound is isotypic with the Co, Ni, Cu, and Zn analogues.

Poly[hexa-?-acetato-bis-(dimethyl sulfoxide)-trimanganese(II)].

Project description:In the title complex, [Mn(3)(CH(3)CO(2))(6)(C(2)H(6)SO)(2)](n), the Mn(II) ions exhibit similar MnO(6) octa-hedral coordination geometries but with different coordination environments. One type of Mn(II) ion is surrounded by five acetate groups and a terminal dimethyl sulfoxide group, while the other lies on a twofold axis and is coordinated by six O atoms from three symmetry-related acetate ions. The acetate anions exhibit three independent bridging modes, which flexibly bridge the Mn(II) ions along the c-axis direction, forming an infinite chain structure; the chains are further inter-connected through weak C-H?O and C-H?S hydrogen-bonding inter-actions.

Project description:The asymmetric unit of the title salt, [Mn(C2H6OS)6]I2, consists of one Mn(II) ion, six O-bound dimethyl sulfoxide (DMSO) ligands and two I(-) counter-anions. The isolated complex cations have an octa-hedral configuration and are grouped in hexa-gonally arranged rows extending parallel to [100]. The two I(-) anions are located between the rows and are linked to the cations through two weak C-H?I inter-actions.

Hexa-kis-(dimethyl sulfoxide-?O)nickel(II) bis-(2,2-dicyano-ethene-1,1-dithiol-ato-?S,S')nickelate(II).

Project description:The reaction of NiCl(2)·6H(2)O with sodium 2,2-dicyano-ethene-1,1-dithiol-ate [Na(2)(i-mnt)] in dimethyl sulfoxide produces the title complex, [Ni(C(2)H(6)OS)(6)][Ni(C(4)N(2)S(2))(2)]. There is half each of an [Ni(C(2)H(6)OS)(6)](2-) complex anion and an [Ni{(CH(3))(2)SO}(6)](2+) complex cation in the asymmetric unit. The i-mnt ligand coordinates in a bidentate manner to the Ni atom in the anion through the two chelating S atoms in an approximate square-planar geometry. The Ni atom in the complex cation has an octahedral coordination environment with six dimethyl sulfoxide mol-ecules as ligands.

Hexa-kis-(dimethyl sulfoxide-?O)thallium(III) trinitrate.

Project description:The title compound, [Tl(C(2)H(6)OS)(6)](NO(3))(3), consists of six dimethyl sulfoxide (DMSO) mol-ecules coordinated to a Tl(III) atom, which lies on a axis, and three nitrate anions (3. symmetry) to neutralize the charge. The coordination polyhedron around the Tl(III) atom is octa-hedral, defined by six O atoms of the DMSO mol-ecules. In the crystal structure, C-H?O hydrogen bonds are observed. One of the nitrate groups exhibits half-occupation.

Hexa-kis-(dimethyl sulfoxide-?O)calcium ?(6)-oxido-dodeca-kis-?(2)-oxido-hexa-oxido-hexa-tungstate(VI).

Project description:In the title compound, [Ca(C(2)H(6)OS)(6)][W(6)O(19)], the cation and anion both have a crystallographically imposed centre of symmetry. The Ca(II) atom in the cation is coordinated by six O atoms from six dimethyl sulfoxide ligands in a distorted octa-hedral geometry. The [W(6)O(19)](2-) isopolyanion possesses the well-known Lindqvist structure in which each W(VI) atom is coordinated by four ?(2)-O, one terminal O and one ?(6)-O atom.

Poly[[hexa-kis-(?-benzene-1,4-dicarboxyl-ato)octa-kis-(N,N-dimethyl-acetamide)-hexa-manganese(II)] monohydrate].

Project description:In the title compound, {[Mn(6)(C(8)H(4)O(4))(6)(C(4)H(9)NO)(8)]·H(2)O}(n), two of the Mn atoms are six-coordinated by six O atoms from three benzene-1,4-dicarboxyl-ate (bdc) ligands and two trans DMA (dimethyl-acetamide) mol-ecules, whereas two other Mn atoms, located on inversion centers, are both in octa-hedral coordinations by six bdc O atoms. The discrete trinuclear manganese secondary building units (SBU) of Mn(3)(O(2)CR)(6) ({-Mn-Mn-Mn-}) are linked through bdc ligands, forming a chain, while the discrete trinuclear SBU of {-Mn-Mn-Mn-} are bridged, forming another chain]. The two types of chains are linked through bdc ligands, resulting in the formation of a layer with 3(6) topology. Weak O-H?O and O-H?N hydrogen-bonding inter-actions involving the disordered water molecule (half-occupation) extend the two-dimensional layers into a three-dimensional supra-molecular framework.

Octa-kis(dimethyl sulfoxide-κO)cerium(III) μ(6)-oxido-dodeca-μ(2)-oxido-hexa-oxidohexa-molybdate(VI) dimethyl sulfoxide tetrasolvate.

Project description:The title complex, [Ce(C(2)H(6)OS)(8)](2)[Mo(6)O(19)](3)·4C(2)H(6)OS, was obtained as a byproduct of the reaction of [(C(4)H(9))(4)N](2)[Mo(6)O(19)] with Ce(NO(3))(3)·6H(2)O and phthalic acid in dimethyl-sulfoxide solution. The asymmetric unit consists of a complex [Ce(C(2)H(6)OS)(8)](3+) cation, one and a half of the Lindqvist-type [Mo(6)O(19)](2-) polyanions and two dimethyl-sulfoxide solvent mol-ecules; the half polyanion lies on an inversion center. The Ce(3+) ion is coordinated by eight dimethyl-sulfoxide ligands through the O atoms in the form of a distorted square antiprism. The Ce-O bond lengths range from 2.429 (6) to 2.550 (5) Å. The cohesion of the structure is ensured by S⋯O [3.115 (6), 3.242 (10) and 3.12 (3) Å], O⋯O [3.037 (10) Å] and C-H⋯O inter-actions between cations and anions. The S and C atoms of a dmso ligand are disordered over three sites in a 0.45:0.30:0.25 ratio. The dimethyl-sulfoxide solvent mol-ecules are highly disordered and could not be modelled successfully; their contribution was therefore removed from the refinement using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. Potential solvent-accessible voids of 500.0 Å(3) occur in the crystal structure.

Poly[tris-(?-4,4'-bi-pyridine-?(2) N:N')bis(dimethyl sulfoxide-?O)tetra-kis-(thiocyanato-?N)dicobalt(II)].

Project description:The asymmetric unit of the title compound, [Co2(NCS)4(C10H8N2)3(C2H6OS)2] n , consists of one Co(II) atom, two thio-cyanate anions, one dimethyl sulfoxide mol-ecule and one and a half 4,4'-bi-pyridine mol-ecules. The half-molecule is completed by inversion symmetry. The Co(II) atom is coordin-ated in a distorted octa-hedral geometry by two N atoms from two thio-cyanate anions, one O atom from dimethyl sulfoxide as a terminal ligand and three N atoms from three 4,4'-bi-pyridine mol-ecules as bridging ligands linking the cations, with a Co?Co separation of 11.5964?(5)?Å. This generates a two-dimensional structure parallel to (-103). A C-H?S hydrogen bond links the layers into a three-dimensional supra-molecular framework. The layers are stacked in an ABC fashion preventing the occurrence of inter-layer void space and hence leading to the absence of lattice solvent and/or organic guest mol-ecules in the structure.

Crystal structure of hexa-kis-(dimethyl sulfoxide-κO)cobalt(II) bis-[tri-chlorido-(quinoline-κN)cobaltate(II)].

Project description:There are few reports that describe crystal structures of compounds containing cobalt complexed to either dimethyl sulfoxide (Me2SO) or quinoline (C9H7N). The title compound, [Co(C2H6OS)6][CoCl3(C9H7N)]2, is a cobalt salt in which the metal ion is complexed to both Me2SO and quinoline. In particular, we observed that anhydrous cobalt(II) chloride reacts with quinoline in Me2SO to form a salt that is to be formulated as [CoII(Me2SO)6]2+{[CoIICl3quinoline]2-}. The CoII atom in the cation portion of this mol-ecule lies on a inversion center and is bound to the O atoms of six Me2SO moieties in an octa-hedral configuration, while the CoII atom in the anion is attached to three chloride ligands and one quinoline moiety in a tetra-hedral arrangement.
