Selected Abstracts[(2E)-2-Benzylidenehydrazino]tricyclohexylphosphonium chlorideACTA CRYSTALLOGRAPHICA SECTION C, Issue 2 2001Andrei S. Batsanov In the title compound, C25H40N2P+·Cl,, the cation structure (at 150,K) is intermediate between those of the iminophosphorane and the ylide, consistent with delocalization of the positive charge between the P and the adjacent N atoms. The cation and anion are linked by a strong N,H,Cl hydrogen bond. [source] Supramolecular aggregation in 4,4,-bipyridin-1,1,-ium dichloride, 4,4,-bipyridin-1,1,-ium dinitrate and 4,4,-bipyridin-1-ium bromideACTA CRYSTALLOGRAPHICA SECTION B, Issue 5 2003Peter Abeta Iyere 4,4,-Bipyridin-1,1,-ium dichloride [C10H10Cl2N2 (I)] and 4,4,-bipyridin-1,1,-ium dinitrate [C10H10N4O6 (II)] have been prepared and the crystal structures determined at 90.0,(2),K. Molecules of (I) are linked by two chlorine-bridged, three-centered N,H,Cl hydrogen bonds into chains along the b axis. The chains are coupled by weak C,H,Cl interactions into a molecular ladder along the c direction. In (II) each nitrate is coordinated to four bipyridinium ions through the interplay of the N,H,O and C,H,O contacts, resulting in a three-dimensional zigzag sheet on the ab plane. The sheets stack along the c axis. In 4,4,-bipyridin-1-ium bromide monohydrate [C10H9N2+·Br,·H2O (III)] the bipyridinium ions are linked by three-center N,H,N, hydrogen bonds in a head-to-tail fashion to form chains along the b axis. The chains are linked by C,H,Br and C,H,OH2 into a three-dimensional framework.

Trzeciak The title compound, [Pd2(C12H10O3P)2Cl2(C12H11O3P)2], consists of a dinuclear ,-chloro-bridged palladium unit with two diphenoxyphosphinite groups per Pd atom, linked together by a hydrogen bond. The asymmetric unit contains one half of the molecule, with the other half generated by an inversion centre. The geometry around the P atoms may be described as distorted tetrahedral. Adjacent molecules of the complex are linked by weak C,H,O and C,H,Cl hydrogen bonds. The structure is additionally stabilized by ,,, stacking interactions between the aryl rings. These interactions form a herring-bone pattern in the crystal structure. [source] cis -Amminedichloroisopropylamineplatinum(II) by X-ray powder diffraction analysisACTA CRYSTALLOGRAPHICA SECTION C, Issue 6 2006Sergei D. Kirik The title compound, [PtCl2(C3H9N)(NH3)], was obtained from potassium tetrachloroplatinate(II) by a two-step route. Ab initio crystal structure determination was carried out using X-ray powder diffraction techniques. Patterson and Fourier syntheses were used for the atom locations and the Rietveld technique for the final structure refinement. The Pt coordination is close to planar, with Cl atoms in a cis orientation. Molecules are combined into groups of two molecules, with antiparallel PtN2Cl2 planes and a shortest Pt,Pt distance of 3.42,Å. The molecule groups are packed in a parquet motif into corrugated layers parallel to ab. The molecules in the layers are linked by H,N,Cl hydrogen bonds.

In both crystal structures, the 1,3-thiazolidine ring adopts a half-chair conformation. The crystal structures are stabilized by weak C,H,O and C,H,Cl hydrogen bonds in (V) and (IX), respectively. [source] Transition metal complexes with thiosemicarbazide-based ligands.ACTA CRYSTALLOGRAPHICA SECTION C, Issue 6 2002XLIII. In the title compound, [ZnCl(C2H7N3S)2]Cl, the ZnII ion is five-coordinated in a distorted trigonal,bipyramidal arrangement, with the hydrazine N atoms located in the apical positions. The structure is stabilized by N,H,Cl hydrogen bonds, which involve both the Cl atoms and all the hydrogen donors, except for one of the two thioamide N atoms. A comparison of the geometry of thiosemicarbazide and S -methylisothiosemicarbazide complexes with ZnII, CuII and NiII shows the pronounced influence of the hydrogen-bond network on the coordination geometry of ZnII compounds. [source] trans -Bis(benzylamine)dichloropalladium(II) bis(dimethyl sulfoxide) solvateACTA CRYSTALLOGRAPHICA SECTION C, Issue 9 2000Andreas Decken The title compound, [PdCl2(C7H9N)2]·2C2H6OS, crystallizes with two molecules of dimethyl sulfoxide (DMSO) in monoclinic space group P21/n. The Pd complex is centrosymmetric and thus the phenyl rings of the benzylamine ligands are exo with respect to one another. The crystal packing reveals NH,O and CH,Cl hydrogen bonds between the organometallic molecule and the DMSO molecules, resulting in infinite chains. The distances of the ortho -H atoms on the phenyl ring to the metal center are in the range 4.71,5.34,Å, precluding any significant intramolecular Pd,H interactions. [source] | ||||||||||
