Three luminescent polymorphs based on a new copper(I) complex Cu(2-QBO)(PPh3)PF6 (1, PPh3 = triphenylphosphine, 2-QBO = 2-(2'-quinolyl)benzoxazole) have been synthesized and characterized by FT-IR, UV-vis, elemental analyses, and single-crystal X-ray diffraction analyses. Each polymorph can reversibly convert from one to another through appropriate(More)
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)
In the title complex, [Cu(C(4)H(5)NO(4))(C(6)H(6)N(2)O)(H(2)O)], conventionally abbreviated Cu(IDA)(4-OXPy)(H(2)O), where IDA is imino-diacetate and 4-OXPy is 4-(hy-droxy-imino-meth-yl)pyridine, the Cu(II) atom exhibits a distorted square-pyramidal coordination geometry, which is constructed from two O atoms and one N atom from a IDA ligand, one N atom from(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 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)
Two novel porous three-dimensional (3D) quaternary thioantimonates(III) ACuSb2S4 (A = Rb, Cs) were successfully synthesized by employing the neutral surfactant PEG-400 (PEG = polyethyleneglycol) as reaction media, these are significantly different from the known quaternary A-Cu-Sb-S thioantimonates(III) with two-dimensional (2D) crystal structures. This is(More)
The title dinuclear complex, (aqua-1κO)tetrakis(μ-2,3-diphenylprop-2-enoato-1:2κ(2)O:O')bis(2,3-diphenylprop-2-enoato)-1κO;2κO-(ethanol-2κO)bis(1,10-phenanthroline)-1κ(2)N,N';2κ(2)N,N'-dilanthanum(III), [La(2)(C(15)H(11)O(2))(6)(C(12)H(8)N(2))(2)(C(2)H(5)OH)(H(2)O)], contains two similar La(III) centres with distorted [LaO(6)N(2)] bicapped(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)
In the title Cu(II) complex, [Cu(C19H14O3P)2(C3H7NO)(H2O)2], the molecule is bisected by a twofold axis relating the two 2-(diphenylphosphoryl)benzoate (ODPPB) ligands. The asymmetric unit consists of a Cu(II) metal centre on the symmetry axis, an ODPPB ligand, one water ligand and one dimethylformamide (DMF) ligand (disordered around the twofold axis). The(More)
