Crystal structure of bis-{μ-4-methyl-N'-[3-(oxido-imino)-butan-2-yl-idene]benzene-sulfono-hydrazidato}bis-[(dimethyl sulfoxide-κO)copper(II)].

ABSTRACT: In the title compound, [Cu2(C11H13N3O3S)2(C2H6OS)2], the Cu(II) cation is N,N',O-chelated by a deprotonated hy-droxy-imino-tosyl-hydrazone ligand and coordinated by a dimethyl sulfoxide mol-ecule. One O atom from the adjacent hy-droxy-imino-tosyl-hydrazone ligand bridges the Cu(II) cation, forming the centrosymmetric dimeric complex. The cation is in an overall distorted N2O3 square-pyramidal coordination environment. The methyl-benzene ring is twisted with respect to the hydrazine fragment, with a dihedral angle of 89.54 (9)° between the planes. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯S inter-actions. Weak π-π stacking is also observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.9592 (17) Å.

N'-[3-(Hy-droxy-imino)-butan-2-yl-idene]-4-methyl-benzene-1-sulfono-hydrazide.

Project description:In the title compound, C(11)H(15)N(3)O(3)S, the C-S-N(H)-N linkage is nonplanar, the torsion angle being 75.70?(12)°. The compound has two almost planar fragments linked to the S atom: the hydrazone-derivative fragment [(HONC(4)H(6))N-N(H)-] and the tolyl fragment (C(7)H(7)-) have maximum deviations from the mean plane through the non-H atoms of 0.0260?(10) and 0.0148?(14)?Å, respectively. The two planar fragments make an inter-planar angle of 79.47?(5)°. In the crystal, mol-ecules are connected through inversion centers via pairs of N-H?O and O-H?N hydrogen bonds.

μ-Oxido-bis-[bis-(phenanthroline-κN,N')(sulfato-κO)iron(III)] octa-hydrate.

Project description:The title complex, [Fe(2)O(SO(4))(2)(C(12)H(8)N(2))(4)]·8H(2)O, contains two unique Fe(III) cations, one oxide anion, four 1,10-phenanthroline (phen) ligands, two coordinated sulfate anions and eight lattice water mol-ecules. Each Fe(III) ion has an approximate octa-hedral geometry, coordinated by four N atoms from two phen mol-ecules, two O atoms from oxide and sulfate anions, respectively. The parallel phen mol-ecules form two-dimensional supermolecules through π-π stacking inter-actions [centroid-centroid distances = 3.684 (3), 3.711 (3), 3.790 (3), 3.847 (3), 3.746 (3), 3.732 (3) and 3.729 (3) Å]. This architecture is further stabilized by O-H⋯O hydrogen bonds involving the lattice water mol-ecules and sulfate O atoms.

Hexa-μ(2)-acetato-κO:O'-(azido-κN)bis-(methanol-κO)-μ(3)-oxido-trichromium(III) methanol monosolvate.

Project description:In the crystal structure of the title complex, [Cr(3)(CH(3)CO(2))(6)(N(3))O(CH(3)OH)(2)]·CH(3)OH, the trinuclear core has a central O atom; two methanol mol-ecules and an azide ion are coordinated to the Cr(III) atoms in the core. The three Cr(III) atoms form vertices of a nearly equilateral triangle. Each of the six acetate carboxyl-ate groups bridges a Cr-O-Cr fragment. In the crystal, the molecules inter-act with methanol solvent mol-ecules through O-H⋯O and O-H⋯N hydrogen bonds, forming a two-dimensional hydrogen-bonded network parallel to (100).

Project description:A new dinuclear triphenyl-anti-mony(V) derivative with an oxide bridge, [Sb(2)(C(6)H(5))(6)(C(6)H(3)ClNO(2))(2)O], has been synthesized. Each Sb atom is five-coordianted by three C atoms and two O atoms in a distorted trigonal-bipyramidal geometry. Metal centers are bridged by a μ(2)-oxide functionality, and phenyl substituents on Sb atoms are in an staggered arrangement. The Sb-O-Sb bridge displays a bent geometry with an angle of 165.1 (4)°. Mol-ecules inter-act in the crystal through weak C-H⋯O and C-H⋯N inter-molecular hydrogen bonds.

Hexa-kis-(dimethyl-formamide-κO)manganese(II) μ-oxido-bis-[trichlorido-ferrate(III)].

Project description:The title compound, [Mn(C(3)H(7)NO)(6)][Fe(2)Cl(6)O], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes with Schiff base ligands using manganese powder and FeCl(3)·6H(2)O as starting materials. In the [Fe(2)OCl(6)](2-) anion, the O atom and the Fe atom occupy positions with site symmetry [Formula: see text] and 3, respectively, resulting in a linear Fe-O-Fe angle and a staggered conformation. The octa-hedrally surrounded cation (site symmetry [Formula: see text]) and the [Fe(2)Cl(6)O](2-) anion are alternately stacked along [001].

Crystal structure of μ-oxalodi-hydroxamato-bis-[(2,2'-bipyrid-yl)(di-methyl sulfoxide-κO)copper(II)] bis-(perchlorate).

Project description:The centrosymmetric binuclear complex, [Cu2(C2H2N2O4)(C10H8N2)2(C2H6OS)2](ClO4)2, contains two copper(II) ions, connected through an N-deprotonated oxalodi-hydroxamic acid dianion, two terminal 2,2'-bi-pyridine ligands, and two apically coordinating dimethylsulfoxide mol-ecules. Two non-coordinating perchlorate anions assure electrical neutrality. The copper(II) ions in the complex dication [Cu2(C10H8N2)2(μ-C2H2N2O4)(C2H6SO)2](2+) are in an O2N3 square-pyramidal donor environment, the Cu-Cu separation being 5.2949 (4) Å. Two hydroxamate groups in the deprotonated oxalodi-hydroxamic acid are located trans to one each other. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the complex cations to the perchlorate anions. Further C-H⋯O hydrogen bonds combine with π-π contacts with a centroid-to-centroid separation of 3.6371 (12) Å to stack the mol-ecules along the a-axis direction.

Project description:In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help to stabilize the crystal structure.

Di-μ-benzoato-κO,O':O';κO:O,O'-bis[aqua-bis-(benzoato-κO,O')(dimethylformamide-κO)europium(III)].

Project description:The title dimeric complex, [Eu(2)(C(7)H(5)O(2))(6)(C(3)H(7)NO)(2)(H(2)O)(2)], is centrosymmetric, implying that pairs of equivalent Eu(3+) ions and ligands lie trans to each other and that the two Eu(3+) ions have exactly the same coordination environment. Each Eu(3+) ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylformamide and one water molecule. The coordination polyhedron of each Eu(3+) ion can be described with a distorted monocapped square-anti-prismatic geometry. The mol-ecular structure is stabilized by intra- and inter-molecular hydrogen bonds between the water mol-ecules and benzoate O atoms.

The Cl atoms are involved in weak anion-cation C-H⋯Cl inter-actions, giving a network structure.
