Disodium tris-(dioxidomolybdenum) bis-(diarsenate).

ABSTRACT: The asymmetric unit of the title compound, Na(2)(MoO(2))(3)(As(2)O(7))(2), is composed of two cyclic MoAs(2)O(11) units and an MoO(6) corner-sharing octa-hedron. The anionic framework can be decomposed into two types of layers, viz. MoO(2)As(2)O(7) and Mo(2)As(2)O(14), which use mixed Mo-O-As and As-O-Mo bridges to achieve a new three-dimensional structure with two types of large channels in which the Na(+) cations are located. Two O atoms are disordered and are located in two positions close to their initial positions with occupancy ratios of 0.612?(17):0.388?(17) and 0.703?(12):0.298?(12).

Disodium tetra-aqua-bis(sulfato)iron(II).

Project description:In the title compound, [FeNa(2)(SO(4))(2)(H(2)O)(4)], the Fe(2+) cation is situated on a centre of inversion and is hexa-coordinated by four O atoms from water mol-ecules and two O atoms from two sulfate anions in an octa-hedral geometry. The coordination environment of Na(+) comprises six O atoms in a more distorted octa-hedral arrangement, with Na-O distances between 2.368 (1) and 2.612 (1) Å. The structure contains an extensive three-dimensional network of O-H⋯O hydrogen bonds.

Poly[[μ(10)-2,3-bis(carboxymethyl)butanedioato]disodium].

Project description:The asymmetric unit of the title compound, [Na(2)(C(8)H(8)O(8))](n), contains one Na(+) ion and half of a 2,3-bis(carboxymethyl)butanedioate (H(2)BTC(2-)) dianion, which lies on a center of symmetry. The dianion exhibits a μ(10)-bridging mode. Each Na atom lies in a NaO(6) octa-hedron defined by six O atoms from five dianions. Adjacent NaO(6) octa-hedra share a common O-O edge, generating a biocta-hedron; adjacent biocta-hedra are O-O edge-connected to one another, building up a chain along [001]. The chains are connected by adjacent H(2)BTC(2-) anions into a three-dimensional framework. The structure is further stabilized by O-H⋯O hydrogen bonds.

Disodium calcium dinickel(II) bis-[diphosphate(V)] deca-hydrate.

Project description:In the title compound, Na(2)CaNi(2)(P(2)O(7))(2)(H(2)O)(10), there are two distinct P-atom sites, each tetra-hedrally coordinated by four O atoms. The resulting phosphate tetra-hedra link through a common O atom, forming a [P(2)O(7)](4-) diphosphate unit. The Ni-O coordination is square pyramidal with four O atoms from two diphosphate groups in equatorial positions and the vertex occupied by a water O atom. The (P(2)O(7))(H(2)O) units link the Ni atoms, forming a chain of pyramids and tetra-hedra. As a result of the d-glide and twofold-axis symmetry of space group Fdd2, the chains propagate along [101] and [10], and chains in adjacent layers are mutually orthogonal. The Ca cation, located on a rotation axis, and the Na cation are each octa-hedrally coordinated by four O atoms and two waters. The Ni-chain arrangement is stabilized by Ca and Na coordination and a network of O-H⋯O hydrogen bonds.

Dioxidomolybdenum(VI) complex featuring a 2,4-di-fluoro-substituted amine bis-(phenolate) ligand.

Project description:Synthetic complexes containing a cis-[MoO2]2+ core are well-established models for the molybdenum co-factor (Moco). Here we report the crystal structure of such a model complex bearing a tetra-dentate amine bis-(phenolate) ligand with fluorine substituents on the phenolate rings, namely, [2,2'-({[2-(di-methyl-amino)-eth-yl]aza-nedi-yl}bis-(methyl-ene))bis-(4,6-di-fluoro-phenolato)]dioxidomolybden-um(VI)), [Mo(C18H18F4N2O2)O2]. Distortion from idealized octa-hedral symmetry about the Mo center is evident in the large O=Mo=O angle [108.54 (4)°] and the small N-Mo-Ophenolate angles [79.79 (4), 81.21 (3), 77.83 (3), and 84.59 (3)°]. The dihedral angle between the phenolate rings is 60.06 (4)°, and π-π stacking is observed between aromatic rings related by inversion (1 - x, 1 - y, 1 - z). The lower data-collection temperature of 150 K vs room-temperature data collection reported previously [KOWXIF; Cao et al. (2014 ▸). Transit. Met. Chem. 39, 933-937] and larger 2θ range for data collection (5.8-66.6° versus 6-54.96°) led to a structure with lower R 1 and ωR 2 values (0.019 and 0.049 vs 0.0310 and 0.0566 for KOWXIF). Comparison of the metrical parameters with KOWXIF suggests that this dataset offers a more realistic depiction of bonding within the MoVI=O moiety.

Barium zinc diarsenate.

Project description:The title compound, BaZnAs(2)O(7), belongs to the family of isotypic series of compounds adopting the general formula M1(2+)M2(2+)X(2)O(7) (M1(2+) = Ca, Sr, Ba or Pb; M2(2+) = Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn or Cd; X = P or As). Suitable single crystals were prepared under hydro-thermal conditions. The framework structure is characterized by corner-sharing ZnO(5) square pyramids and As(2)O(7) groups where the Zn atoms occupy channels. X-ray diffraction analysis of single crystals twinned by non-merohedry [twin plane is (100)] yielded formula BaZnAs(2)O(7). Raman spectra confirmed the presence of a non-linear As-O-As linkage.

{2,2'-[(2,2-Dimethyl-propane-1,3-di-yl)-bis-(nitrilo-methyl-idyne)]-diphenolato}-dioxidomolybdenum(VI).

Project description:In the structure of the title compound, [Mo(C(19)H(20)N(2)O(2))O(2)], the Mo atom exhibits oxidation state +VI and is surrounded by two O atoms and the tetra-dentate Schiff base ligand 2,2'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate in a distorted octa-hedral configuration. An intra-molecular C-H⋯O hydrogen bond between a methyl-ene group and one O atom of the O=Mo(VI)=O unit, as well as additional inter-molecular hydrogen bonds between neighboring mol-ecules, lead to a weakly bonded inversion-symmetric dimeric structure.

In the crystal structure, each Mo polyhedron has a square-anti-prismatic shape, while the Co complexes show distorted octa-hedral geometry with an occupancy of 50%. One of the Co atoms resides on a crystallographic inversion centre.

Tris(piperazinediium) bis-[tris-(pyridine-2,6-dicarboxyl-ato)neodymate(III)] 15.33-hydrate.

Project description:The title compound, (C(4)H(12)N(2))(3)[Nd(C(7)H(3)NO(4))(3)](2)·15.33H(2)O or (pipzH(2))(3)[Nd(pydc)(3)](2)·15.33H(2)O (in which pipz is piperazine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of NdCl(3)·6H(2)O with the proton-transfer compound (pipzH(2))(pydc) in aqueous solution. The nine donor atoms of the three pydc(2-) ligands form a distorted tricapped trigonal-prismatic arrangement around the Nd(III) center. Considerable C-O⋯π stacking inter-actions between CO groups of carboxyl-ate fragments and aromatic rings of pydc(2-) with distances of 3.135 (5)-3.255 (5) Å are observed. In the crystal structure, a wide range of hydrogen-bonding [of the types O-H⋯O, N-H⋯O and C-H⋯O, with D⋯A distances ranging from 2.608 (10) to 3.278 (7) Å], ion-pairing and C-O⋯π stacking interactions connect the various components into a supra-molecular structure. There is a high degree of solvent disorder in the structure; the occupancies of five water molecules refined to 0.6, 0.5, 0.4, 0.25 and 0.25.

Bis[tris-(1,10-phenanthroline)nickel(II)] tris-[dicyanidoargentate(I)] nitrate 4.2-hydrate.

Project description:The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H⋯O and C-H⋯N inter-actions may help to establish the packing.

New mixed aluminium-chromium diarsenate.

Project description:Potassium chromium aluminium diarsenate, KCr1/4Al3/4As2O7, was prepared by solid-state reaction. The structure consists of (Cr1/4/Al3/4)O6 octa-hedra and As2O7 diarsenate groups sharing corners to build up a three-dimensional anionic framework. The potassium cations are located in wide channels running along the c-axis direction. The crystal structure is isostructural with the triclinic AIMIIIX2O7 (AI = alkali metal; MIII = Al, Cr, Fe; X = As, P) compounds. However, the MIII octa-hedrally coordinated site is 25% partially occupied by chromium and 75% by aluminium.
