5,5'-(Ethyne-1,2-di-yl)diisophthalic acid dimethyl sulfoxide tetra-solvate.

ABSTRACT: In the title compound, C18H10O8·4C2H6OS, the mid-point of the triple bond of the main mol-ecule is located on a special position, i.e. about an inversion center. The carboxyl groups are twisted slightly out of the planes of the aromatic rings to which they are attached, making dihedral angles of 24.89?(1) and 7.40?(2)°. The cystal packing features strong O-H?O hydrogen bonds, weaker C-H?O inter-actions and O?S contacts [3.0981?(11)?Å] and displays channel-like voids extending along the a-axis direction which contain the dimethyl sulfoxide solvent mol-ecules.

(E)-5,5'-(Diazene-1,2-di-yl)diisophthalic acid N,N-dimethyl-formamide disolvate.

Project description:The title compound, C(16)H(10)N(2)O(8)·2C(3)H(7)NO, was synthesized by the reductive condensation reaction of 5-nitro-isophthalic acid in the presence of NaOH. The tetra-acid mol-ecule, which has a crystallographically imposed centre of symmetry, adopts an E configuration with respect to the azo group. In the crystal packing, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen-bonding inter-actions, forming chains propagating in [20].

Di-?-chlorido-bis-[(2,2'-bipyridine-5,5'-dicarb-oxy-lic acid-?(2)N,N')chloridocopper(II)] dimethyl-formamide tetra-solvate.

Project description:In the title compound, [Cu(2)Cl(4)(C(12)H(8)N(2)O(4))(2)]·4C(3)H(7)NO, which contains a chloride-bridged centrosymmetric Cu(II) dimer, the Cu(II) atom is in a distorted square-pyramidal 4 + 1 coordination geometry defined by the N atoms of the chelating 2,2'-bipyridine ligand, a terminal chloride and two bridging chloride ligands. Of the two independent dimethyl-formamide mol-ecules, one is hydrogen bonded to a single -COOH group, while one links two adjacent -COOH groups via a strong accepted O-H?O and a weak donated C(O)-H?O hydrogen bond. Two of these last mol-ecules and the two -COOH groups form a centrosymmetric hydrogen-bonded ring in which the CH=O and the -COOH groups by disorder adopt two alternate orientations in a 0.44:0.56 ratio. These hydrogen bonds link the Cu(II) complex mol-ecules and the dimethyl-formamide solvent mol-ecules into infinite chains along [-111]. Slipped ?-? stacking inter-actions between two centrosymmetric pyridine rings (centroid-centroid distance = 3.63?Å) contribute to the coherence of the structure along [0-11].

Crystal structure of dimethyl <i>N</i>,<i>N</i>'-[(ethyne-1,2-di-yl)bis-(1,4-phenyl-enecarbon-yl)]bis-(l-alaninate).

Project description:The di-phenyl-ethyne unit of the title mol-ecule, C24H24N2O6, deviates slightly from planarity. The l-alanine moieties adopt distorted helical conformations of opposite winding direction. Infinite ribbons of N-H⋯O=C-connected mol-ecules represent the basic supra-molecular entities of the crystal structure. These aggregates are linked by C-H⋯O hydrogen bonds involving the oxygen atoms of the methyl carboxyl-ate units. The crystal studied was refined as an inversion twin.

Dichloridobis{2-[(dimethyl-amino)-meth-yl]phen-yl}bis-{2-[(dimethyl-aza-nium-yl)meth-yl]phen-yl}di-μ-hydroxido-di-μ(3)-oxido-tetra-phenyl-tetra-tin(IV) dichloride deuterochloro-form deca-solvate.

Project description:The ladder-like structure of the tetranuclear title compound, [Sn(4)(C(6)H(5))(4)Cl(2)O(2)(OH)(2)(C(9)H(13)N)(2)(C(9)H(12)N)(2)]Cl(2)·10CDCl(3), consists of two five- and two six-coordinated Sn(IV) atoms bridged by oxide or hydroxide groups. The chelating ligands reveal rather strong Sn-N bonds [2.517 (4) Å], but the protonated dimethylamino groups in the periphery of the complex show no interaction with the metal atoms. The complex cation is located on an inversion centre. The chloride anion is linked to the complex mol-ecule by strong intra-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds. Five independent deuterochloroform accompany the complex, two of them are disordered [occupancy ratios 0.63 (2):0.27 (2) and 0.60 (2):0.40 (2)].
