The asymmetric unit of the title compound, C(44)H(32)P(2), conventionally abbreviated BINAP, is one half of the complete chiral BINAP mol-ecule, which adopts a C2 crystallographic point-group symmetry with a twofold axis splitting the mol-ecule in two identical halves; a center of symmetry between mol-ecules further determines the racemic pairs. There are(More)

In the crystal structure of the title monohydrate salt, [ZnCl(C(12)H(8)N(2))(2)][BiCl(4)(C(12)H(8)N(2))]·H(2)O, the ionic components are linked into three-dimensional supra-molecular channels by five pairs of C-H⋯Cl hydrogen bonds and π-π stacking inter-actions with an inter-planar distance of 3.643 (2) Å. The solvent water mol-ecules are lodged in the(More)
The solvothermal reaction of copper(I) iodide and 1,10-phenanthroline (phen) in ethanol yielded the title polymeric compound, [CuI(C(12)H(8)N(2))](n). The asymmmetric unit comprises one Cu(+) cation, one I(-) anion and one phen ligand. Each Cu(+) cation is in a distorted tetrahedral coordination by two iodide anions and two N atoms from a bidentate(More)
During our research into novel nonlinear optical materials using 1,10-phenanthroline as an appending ligand on lanthanide iodates, crystals of an infinite layered Dy(III) iodate compound, Dy(IO(3))(3)(H(2)O)·H(2)O, were obtained under hydro-thermal conditions. The Dy(III) cation has a dicapped trigonal prismatic coordination environment consisting of one(More)
The organic mol-ecule of the title compound, C(18)H(14)N(4)O(2)·H(2)O, lies on a center of inversion located at the centre of the central phenyl-ene ring. There are two half-molecules in the asymmetric unit. In the crystal, the mol-ecules are linked through by N-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecule, forming a layer structure. The(More)
The search for the novel metal-organic frameworks (MOFs) materials using tetra-hydro-furan-2,3,4,5-tetra-carboxylic acid (THFTCA) as a versatile multi-carboxyl ligand, lead to the synthesis and the structure determination of the title compound, [Na(H(3)THFTCA)] or [Na(C(8)H(7)O(9))](n), which was obtained by a solution reaction at room temperature.
