Two d10 metal coordination polymers, [Zn(CMTB)(bipy)] · (H2O)2 (1) and [Cd(CMTB)(bipy)] · (H 2O)1.25 (2) (CMTB = 4-[(carboxymethyl) thio]-benzoic acid, bipy = 2,2′-bipyridine) were synthesized under mild mixed solvothermal conditions and characterized by single crystal X-ray diffraction and IR spectroscopy. Compound 1 crystallizes in monoclinic system, space group P21=n with cell parameters: a = 8:1083(16)Å , b = 17.194(3)Å , c = 28.646(6)Å , β = 97.96(3) and Z = 8. It contains a onedimensional (1D) chain structure that is further assembled into a two-dimensional (2D) network by the co-effects of the inter-chain C - H· · ·O hydrogen bonds. Each Zn(II) is six-coordinated to four O atoms from two CMTB ligands, and two N atoms from the 2,2′-bipyridine forming a distorted octahedral coordination geometry. Compound 2 crystallizes in monoclinic system, space group P2/c with cell parameters: a = 19:656(4)Å , β = 10:716(2)Å , c = 19:455(4)Å , b = 94.10(3) and Z = 8. It displays two-dimensional framework\ and metal ion Cd(II) is octahedrally coordinated to four O atoms and two N atoms. Both Compound 1 and 2 are photoluminescent active and their emission properties were also studied. © by Oldenbourg Wissenschaftsverlag, München.

Two types of lanthanide selenidostannates(iv) [Ln2(tepa)2(μ-OH)2Sn2Se6] {Ln = Y(Ia), Pr (Ib), Dy (Ic), Er (Id), Tm (Ie); tepa = tetraethylenepentamine} and [Ln2(tepa)2(μ2-OH)2Cl2]2[Sn4Se10]·4H2O {Ln = Y (IIa), Dy (IIb), Er (IIc), Tm (IId)} have been synthesized under identical solvothermal conditions and characterized structurally. Type I (Ia, Ib, Ic, Id and Ie) displays 1-D neutral chains [Ln2(tepa)2(μ-OH)2Sn2Se6]n, while type II (IIa, IIb, IIc and IId) contains discrete adamantane-like [Sn4Se10]4- ions with binuclear lanthanide complex [Ln2(tepa)2(μ-OH)2Cl2]2+ ions as counterions. Although the solvothermal synthetic methods could result in the formation of various transition-metal chalcogenidometalates, such identical experimental conditions usually result in the only stable phases of lanthanide chalcogenidometalates. Hence, two different lanthanide selenidostannates(iv), obtained under same solvothermal conditions and starting materials, have been first observed in this work. The optical properties of all the compounds have been investigated by UV-vis spectra. This journal is © The Royal Society of Chemistry.

Two new lanthanide complexes [Ln2(tepa)22-OH)2Cl2]Cl2 [Ln = Dy (1), Ho (2); tepa = tetraethylenepentamine] were prepared under solvothermal conditions and characterized by elemental analysis, IR spectroscopy, UV/Vis spectroscopy and single crystal X-ray diffraction. Both 1 and 2 consist of one binuclear [Ln2(tepa)22-OH)2Cl2]2+ ion with cluster [Ln2O2] unit and two Cl− anions. The [Ln2(tepa)22-OH)2Cl2]2+ ion is built up from two [Ln(tepa)Cl]2+ ions linked by two –OH bridging groups. Although some metal complexes of tepa ligand normally appear mononuclear, the binuclear complexes are relatively rare. Hence, both 1 and 2 are the rare examples of the binuclear complexes of tepa ligand. Density functional theory calculation of 1 has been performed. © 2015, Springer Science+Business Media New York.

Three lanthanide thioantimonates [Ho(en)4]SbVS4·0.5en (1, en = ethylenediamine) and [Ln(teta)(en)SbVS4] [Ln = Ho (2), Y (3), teta = triethylenetetramine] were prepared under mild solvothermal conditions and structurally characterized. 1 consists of isolated [Ho(en)4]3+ ion, tetrahedral [SbVS4]3− ion, and free en molecule. Both 2 and 3 contain neutral lanthanide-centred complex, where the tetrahedral anion [SbVS4]3− acts as a chelating ligand to complex [Ln(en)(teta)]3+ cation. Density functional theory calculations for both 2 and 3 have been performed, and the band gaps of 2.02 eV for 1, 1.78 eV for 2 and 1.83 eV for 3 have been derived from optical absorption. © 2015, Springer Science+Business Media New York.

The reported metal complexes of ethyl isonicotinate (L) and its derivative ligands are usually synthetized by two-step method with difficult synthetic routes, but this work first provides one-step solvothermal method for preparation of 1-D copper(I) coordination polymer of ethyl isonicotinate [CuI(L)]n (1), where 1-D stair-step chain [Cu2I2]n is decorated by L ligand. 1 exhibits a fluorescence emission at room temperature, and its theoretical band structure has also been studied. © 2015, Springer Science+Business Media New York.

A new solvothermal method has been successfully prepared crystalline proustite Ag3AsS3 (1) by the reactions of As 2O3, AgNO3 and elemental sulfur in diaminopropane (dap) at 160 °C for 3 days. The crystalline material of 1 was characterized by single crystal X-ray diffraction, powder X-ray diffraction, UV-visible diffuse reflectance spectroscopy, scanning electron microscopy and nonlinear optical determination. The three-dimensional polar framework of 1 is constructed by the linkages of unsymmetrical [AsS3] trigonal pyramids and T-shaped [AgS3] units via bridging S atoms. The absorption edge of 1 is 2.03 eV, exhibiting properties of the semiconductor, and its theoretical band structure has also been studied. Photocatalytic experiments have shown the ability of 1 in the degradation of methylene blue (MB) under visible light (λ > 420 nm). © 2014 Elsevier B.V.
