Bis{μ-2-(1H-indol-3-yl)-N'-[1-(5-methyl-2-oxidophen-yl)ethyl-idene]-aceto-hydraz-idato}bis-[aqua-zinc(II)] dimethyl sulfoxide tetra-solvate.

ABSTRACT: The dinuclear title compound, [Zn(2)(C(19)H(17)N(3)O(2))(2)(H(2)O)(2)]·4C(2)H(6)OS, lies about a center of inversion. The deprotonated monoanion O,N,O-chelates the Zn atom; the hydr-oxy O atom also engages in bonding to the symmetry-related Zn atom so that one N and three O atoms form a square around the metal. The coordination geometry is square-pyramidal, with the apical site occupied by a water mol-ecule. Hydrogen bonds, with the water mol-ecule serving as donor atom, lead to the formation of a linear chain motif. There is an N-H⋯O hydrogen bond between the complex molecule and solvent O atom.

1,5-Bis[(E)-1-(2-hydroxy-phen-yl)ethyl-idene]carbonohydrazide dimethyl sulfoxide solvate.

Project description:The title dimethyl sulfoxide (DMSO) solvate, C(17)H(18)N(4)O(3)·C(2)H(6)OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132?Å); the mol-ecule has non-crystallographic twofold mol-ecular symmetry. This conformation is stabilized by two intra-molecular O-H?N hydrogen bonds. The components of the crystal are connected by N-H?O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C-H?O contacts involving the DMSO H and urea carbonyl atoms, forming a supra-molecular chain along the c axis. The chains associate via C-H?? inter-actions.

Di-μ-nitrato-bis-(μ-octa-ethyl pyro-phospho-ramide)-bis-[aqua-dinitratocalcium(II)].

Project description:The title compound, di-μ-nitrato-κ3 O,O':O;O:O,O'-bis-(μ-octa-ethyl pyro-phos-pho-ramide-κ2 O:O')bis-[aqua-bis-(nitrato-κ2 O,O')calcium(II)], [Ca2(NO3)4(C16H40N4O3P2)2(H2O)2] was obtained as a side product during the work up of the synthesis of octa-ethyl pyro-phospho-ramide and represents the first structurally characterized complex of this ligand. The compound crystallizes in the monoclinic space group P21/n and the asymmetric unit contains one pyro-phospho-ramide mol-ecule and one Ca2+ ion coordinated to two nitrate ions and one water mol-ecule. The complex exists as a dimer with a centre of inversion located between two eight-coordinate calcium(II) centres, which are bridged by two nitrate ions and two octa-ethyl pyro-phospho-ramide ligands. Each Ca2+ cation is also coordinated to a further nitrate anion, acting as a bidentate ligand, and a water mol-ecule. The complexes stack parallel to the a axis and are held in place by a network of inter-molecular O-H⋯O hydrogen bonds also running parallel to a.

Project description:The title complex, [Fe(2)(NCS)(4)(H(2)O)(6)]·6C(8)H(6)ClN(3), comprises two distorted octa-hedral iron(II) centers straddling a crystallographic inversion center and bridged by two aqua O atoms to form a quadrilateral core. The aqua O atom of the core is involved in hydrogen bonds with the triazole N atoms of the solvent mol-ecules, generating one-dimensional ladder motifs, and three inter-molecular C-H⋯S hydrogen bonds, forming a three-dimensional hydrogen-bonding network.

Bis(3,5-dimeth-oxy-2-{[2-(pyridin-2-yl)ethyl-imino-?<i>N</i>]-meth-yl}phenolato-?<i>O</i>)bis-(dimethyl sulfoxide)-manganese(III) perchlorate methanol 0.774-solvate.

Project description:The title compound, [Mn(C16H17N2O3)2(C2H6OS)2]ClO4·0.774CH3OH, comprises a central octa-hedrally coordinated MnIII cation, with two bidentate Schiff base ligands occupying the equatorial positions and two dimethyl sulfoxide (DMSO) ligands occupying the axial positions. There are two independant cations in the asymmetric unit, with the MnIII atoms of both cations being positioned on crystallographic centers of inversion. The perchlorate anion is disordered over two equivalent conformations, with occupancies of 0.744?(3) and 0.226?(3). In addition, there is a methanol solvent mol-ecule in the crystal lattice that is too close to the minor component of the perchlorate anion to be present simultaneously and thus it was refined to have the same occupancy as the major component of this anion. There is a Jahn-Teller distortion which results in Mn-ODMSO axial bond lengths of 2.2365?(12) and 2.2368?(12)?Å in the two cations. In the crystal, inter-molecular ?-? stacking between the non-coordinating pyridine rings of each cation is observed. This ?-? stacking, along with extensive O-H?O hydrogen bonding and C-H?O inter-actions, link the components into a complex three-dimensional array.

The benzotriazole rings in adjacent mol-ecules are almost parallel, with an average inter-planar distance of 3.3400 (2) Å and a centroid-centroid distance of 4.852 (2) Å.
