Acta Crystallographica Section C Crystal Structure Communications, 1997Co-Authors: Joseph L. Stark, Kenton H. WhitmireAbstract:Trans-dibromobis(triphenylphosphine)palladium(II), [(C6H5)3P]2PdBr2 (1), crystalizes in the Triclinic Space Group P-1. Trans-dichlorobis(triphenylphosphine)palladium(II), [(C6H5)3P]2PdCl2 (2) also crystalizes in the Triclinic Space Group P-1. [(C6H5)3P]2PdBr2 is solvated with one THF molecule and has a square planar geometry with the bromide ligands coordinated in a trans configuration. [(C6H5)3P]2PdCl2 is solvated with two chloroform molecules and has a square planar geometry with the palladium, Pd1, residing on an inversion center.

Base-Stabilized Dimeric Organozinc Alkoxides
Journal of Chemical Crystallography, 2010Co-Authors: Stephan Schulz, Ulrich FlörkeAbstract:Dimeric, base-stabilized organozinc alkoxides [dmap-Zn(R)μ-OR]_2 (R = Et 1 ; i -Pr 2 ), were obtained from reactions of ZnR_2 and 4-dimethylaminopyridine (dmap) in the presence of O_2. Their solid state structures were determined by single crystal X-ray diffraction studies. 1 is Triclinic, Space Group P - 1 with a = 8.0639(10) Å, b = 8.3082(11) Å, c = 10.4545(13) Å, α = 70.846(2)°, β = 72.316(2)°, γ = 81.505(2)° and Z = 1. 2 is Triclinic, Space Group P - 1 with a = 8.6381(6) Å, b = 9.2773(7) Å, c = 10.2186(7) Å, α = 112.094(1)°, β = 103.040(1)°, γ = 92.598(1)° and Z = 1. Graphical Abstract Single crystal X-ray analyses of two base-stabilized organozinc alkoxides [dmap-Zn(R)μ-OR]_2 (R = Et 1 ; i -Pr 2 ), which were obtained from reactions of ZnR_2 and 4-dimethylaminopyridine (dmap) in the presence of O_2, are described.

Synthesis and structures of three triphosphonate compounds containing d10 transition metal ions
Journal of Coordination Chemistry, 2008Co-Authors: Shuoping Chen, Yan Guo, Qiao-lan Chen, Liangjie Yuan, Jutang SunAbstract:Three new triphosphonate compounds, [Zn(APTPH4)(2,2′-bipy)(H2O)] · 2H2O (1), [Cd(APTPH4)(2,2′-bipy)(H2O)] · 2H2O (2), and [Zn(APTPH4)(phen)2] · phen · 4H2O (3) (APTPH6 = 1-aminopropane-1,1,3-triphosphonic acid, 2,2′-bipy = 2,2′-bipyridine, phen = 1,10-phenanthroline), are synthesized by a low-temperature hydrothermal method. Compounds 1 and 2 are isomorphous, both one-dimensional (1D) coordination polymers expanded into three-dimensional (3D) supramolecular structures by hydrogen bonds and π–π stacking interactions. Compound 3 is a molecular complex and forms a 3D network through an S-shaped water hexamer.

Ligational aspects of the hydrazide-based Schiff-base, N'-(4-pyridylcarboxamido )-4-( 4'-hexyloxybenzoato)salicylaldimine towards some 3d metal ions and crystal structures of the Schiff-base and Zn(II) complex
Polyhedron, 2008Co-Authors: Angad Kumar Singh, Sanyucta Kumari, K. Ravi Kumar, Balasubramanian Sridhar, T. R. RaoAbstract:Abstract A novel hydrazide-based mesogenic (nematic) Schiff-base, N -(4″-pyridylcarboxamido)-4-(4′-hexyloxybenzoato)salicylaldimine, Hpychbsal (abbreviated as H 2 L) was prepared and its structure studied by elemental analyses, mass, NMR and IR spectra and single crystal XRD (Triclinic Space Group P 1 ¯ with Z = 4) techniques. The Schiff-base behaves as a uninegative bi/tridentate species in its non-mesogenic complexes of the general formula, [M(HL) 2 ] [M = Mn, Co, Ni, Cu and Zn] and as a dinegative tridentate species with Zn(II) in the distorted square-pyramidal complex, [ZnL · 2py], for which the crystal structure was solved (Triclinic Space Group P 1 ¯ with Z = 2). The IR and NMR spectral data imply bonding of HL − and L 2− species through phenolate oxygen and/or amidic oxygen and azomethine nitrogen atoms.
