The crystal structure of the polymeric title compound, {[HgCl(2)(C(18)H(18)N(4))]·C(3)H(7)NO}(n), features an N-heterocyclic ligand which links adjacent HgCl(2) units into a helical chain running along the b axis. The coordination geometry of the Hg(II) atom is a distorted tetra-hedron. The dimethyl-formamide mol-ecule is disordered over two positions in a 1:1 ratio, and is linked to the comple...

Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(n), were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr(6) octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra ...

The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds. There are π-π stacking inter-actions [centroid-centroid distances of 3.718 (2), 3.510 (2) and 3.546 (2) Å] and C-H⋯π inter-actions between the mol-ecules. The water mol...

The reaction of ethyl 3-bromo-3-phenyl-propano-ate with pentane-2,4-dione, in the presence of palladium(II) acetate and triphenyl-phosphine, in dimethyl-formamide, unexpectedly gave the title product, C(16)H(20)O(4). The mol-ecule contains one chiral C atom but the crystal is racemic. In the crystal, neighboring mol-ecules form a chain along [100] through three weak C-H⋯O inter-actions. Further...

The Cu(II) atom is coordinated in a square-pyramidal geometry by a 2,2'-bipyridine and a 2-amino-acetate ligands in the basal plane and by an O atom of N,N-dimethyl-formamide in the apical posit...

The title compound, [Cd(NCS)(2)(C(12)H(8)N(2))(2)], has been obtained from the decomposition reaction of dithio-oxamide in a dimethyl-formamide solution containing 1,10-phenanthroline (phen) and Cd(NO(3))(2)·4H(2)O. Its crystal structure is formed by monuclear Cd(II) entities in which the metal atom is sited on a twofold rotation axis. The Cd(II) atom is six-coordinated in the form of a distort...
