A Dinuclear Zinc(Ⅱ) Complex Derived from a ‘Click' Ligand Containing Phenol,Pyridine and Triazole Donors

A novel 1,2,3-triazolyl-containing ligand(H2L) with long donor arms extending from the central pyridyl linker was synthesized by click cycloaddition of 2,6-bis(azidomethyl)pyridine and 2-((prop-2-yn-1-yl(pyridin-2-ylmethyl)amino)methyl)phenol. Further treatment of the ligand H2 L with zinc(Ⅱ) perchlorate in the presence of triethylamine, followed by anion exchange with Na[BPh4], provided a dinuclear zinc(Ⅱ) complex [Zn2L][BPh4]2·2DMF(1). Complex 1 crystallizes in monoclinic, space group P21 with a = 10.4873(4), b = 14.9078(5), c = 25.8620(9) A, β = 94.566(2)o, V = 4030.5(2) A3, Z = 2, μ = 0.657 mm-1, Dc = 1.324 Mg/m3, T = 296(2) K, C93H91N13B2O4Zn2, Mr = 1607.19, F(000) = 1684, S = 0.958, R = 0.0271 and wR = 0.0607. In the structure of cation, the phenolate oxygen atoms of ligand act as the bridging nodes to form a rhombic Zn2(OAr)2 core.     

Synthesis and Crystal Structure of Bis（（2-methoxy-mercaptomethyl-benzene）hexacarbonyldiiron） Complex

The reaction of [Fe2S2(CO)6] with one equiv.of o-OCH3C6H4CH2Br under the re-duction of LiBHEt3 in dry THF afforded a tetranuclear cluster [(μ4-S){(μ-SCH2(o-OCH3)Ph)Fe2(CO)6}2](1).Complex 1 crystallizes in monoclinic,space group P21/n with a = 16.5623(6),b = 12.8265(5),c = 18.2702(7) ,β = 115.95(1)o,V = 3489.9(4) 3,Z = 4,μ = 1.87 mm-1,Dc = 1.709 Mg/m3,T = 296(2) K,C28H18Fe4O14S3,Mr = 898.03,F(000) = 1800,S = 1.10,R = 0.032 and wR = 0.058.Complex 1 consists of two diiron fragments possessing a {Fe2(CO)6} core.The two diiron units are bridged by an inorganic sulfide in a μ4-S binding mode and the sulfide is in a distorted tetrahedral geometry with the four iron atoms at each corner of the distorted tetrahedral.In its solid state,two types of non-classic intermolecular hydrogen bonding interactions plus a weak π-π stacking interaction led to a 2-D network.     

Syntheses,Structures and Fluorescent Properties of Two 1D Chain Organic Amines and Metal Iodine Organic-inorganic Hybrid Compounds

Two bifunctional amines, 4-(2-aminoethyl)morpholine and histamine, were heated with PbI_2 and BiI_3 in concentrated HI aqueous solution to give one-dimensional(1D) organicinorganic hybrid compounds [(C_6H_(16)N_2O)PbI4]n(1) and [(C_(16)H_(20)N_(20))Bi_2I_(10)](2), respectively. In 1, the [PbI6] octahedra formed double chain anions through sharing-corner and-edge, and the protonated(C_6H_(16)N_2O)~(2+) cations were located at the vicinity of the double chains by hydrogen bonds. In 2, the [BiI_6] octahedra firstly formed dimeric [Bi_2I_(10)]~(4-) anion through sharing edge, and subsequently, the protonated histamine cations worked as bridge to link alternately with [Bi_2I_(10)]~(4-) anion by hydrogen bonds to form organic-inorganic hybrid 1D chains. In addition, compound 1 emitted a green light at the excitation wavelength of 400 nm and the maximum emission wavelength is at 503 nm.
