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 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 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)
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)
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)
Two new quaternary thioarsenates(III), SrAg4 As2 S6 ⋅2 H2 O (1) and BaAgAsS3 (2), have been prepared through a hydrazine-hydrothermal method at low temperature. Compound 1 possesses a two-dimensional (2D) layer network, while compound 2 features a one-dimensional (1D) column structure. The detailed structure analysis indicates that Sr(2+) and Ba(2+) cations(More)
In the title compound, C(24)H(24)N(2)O(2), the five-membered ring of the indoline ring system adopts an envelope conformation with the spiro C atom at the flap. The dihedral angle between the benzene ring of the indoline ring system and the naphthalene ring system is 71.70 (7)°. In the crystal structure, pair of weak C-H⋯O hydrogen bonds link the mol-ecules(More)
In the title complex, [Co(C(12)H(8)N(2))(3)][CoI(C(12)H(8)N(2))(2)(H(2)O)][Bi(3)I(12)], conventionally abbreviated [Co(phen)(3)][CoI(phen)(2)(H(2)O)][Bi(3)I(12)], where phen is 1,10-phenanthroline, the Co(II) atom in one cation is coordinated by six N atoms from three phen ligands in an octa-hedral coordination while the Co(II) atom in the other cation is(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)
