A novel 3-D (3,6)-connected topological architecture, obtained by reacting Cd(ClO4)2 x 6H2O with Htrtr (Htrtr = 3-(1,2,4-triazole-4-yl)-1H-1,2,4-triazole) under solvothermal conditions, presents a non-centrosymmetric polar packing arrangement, resulting in a strong second harmonic generation (SHG) response and ferroelectric property.
A metal-organic framework with the highest connectivity of 2-D topology was first assembled from an octacobalt(II) cluster as a 10-connected node and a new bifunctional ligand 1-(3,5-dicarboxy-phenyl)-4-phenyl-1H-1,2,3-triazole as a 3-connected node as well as "double bridge" linkers.
Two inorganic supramolecular compounds, (Hg(6)P(3))(In(2)Cl(9)) (1) and (Hg(8)As(4))(Bi(3)Cl(13)) (2), which have chiral 3-D host frameworks with guest moieties filling the helical tunnels, have been synthesized. They both have large second-harmonic generation efficiencies, and compound 2 also exhibits obvious single-crystal piezoelectric performance.… (More)
The three-dimensional framework of [Gd(H(2)O)(3)](3)[GdMo(12)O(42)]vdt.3H(2)O, which was synthesized from hydrothermal reaction, is built up from Silverton-type anions linked by nine coordinated gadolinium(III) cations. It is the first time that the paramagnetic lanthanide(III) cation is introduced into the Silverton-type anionic center in the… (More)
Two novel manganese(II) tetrazolate coordination polymers, Mn 3(Hbta) 4(mu 2 -OH) 2(H 2O).2H 2O ( 1) and Mn(bta)(H 2O) ( 2), were obtained by the hydrothermal reaction of MnCl 2.4H 2O with N, N-bis[1(2) H-tetrazol-5-yl]amine (H 2bta) in different pH values. Compound 1 exhibits a 2-D (4,4) layer structure, which is built from binuclear Mn 2(mu 2-OH) 2… (More)
Two structural series, including seven isomorphous heterodinuclear complexes, [Ln(DMSO)4(H2O)3(mu-CN)M(CN)5].H2O ([La-Fe] (1), [Pr-Fe] (2), [Pr-Co] (3), [Nd-Fe] (4), [Nd-Co] (5), [Sm-Fe] (6) and [Sm-Co] (7)), and seven isostructural 2-D stair-like cyano-bridged bimetallic assemblies, [Ln(DMSO)2(H2O)(mu-CN)4M(CN)2]n ([La-Fe]n (8), [Pr-Fe]n (9), [Pr-Co]n… (More)
A new series of novel isostructural metal chalcogenides, K(2)CuIn(3)Se(6) (1), K(2)CuGa(3)Se(6) (2), and K(2)AgIn(3)Se(6) (3), were obtained by a reactive flux technique and structurally characterized. Compounds 1, 2, and 3 crystallize in the space group C2/c of the monoclinic system with eight formula units in a cell: a = 11.445(2) A, b = 11.495(2) A, c =… (More)
The reactions of silver(I) cyanide with tetraalkylammonium salts in anhydrous tetrahydrofuran (THF) under solvothermal conditions and then diffused with ether lead to two novel mixed halogeno(cyano)argentates(I) with efficient luminescence.
Two transition-metal tetrathioarsenate complexes, [Mn(dien)(2)](n)[Mn(dien)AsS(4)](2n).4nH(2)O (1) with one-dimensional water chain and [Mn(en)(3)](2)[Mn(en)(2)AsS(4)][As(3)S(6)] (2) with mixed-valence As(3+)/As(5+) character, have been synthesized and structurally characterized. The tetrathioarsenate(V) anion acts as a novel mu(2)-eta(1),eta(2) ligand in 1… (More)
