Abstract The cobalt(II) complex, [Co(abz)2(SCN)2] 1, has been synthesized by the reaction of cobalt(II) nitrate with ammonium thiocyanate and abz ligands (abz = 2-aminobenzimidazole),
and was fully structurally characterized by elemental analysis, IR spectra, X-ray diffraction and thermogravimetric experiments.
It crystallizes in the triclinic P-1 space group with a = 8.6316(10), b = 9.3426(10), c = 13.254(2) ?, α = 95.793(2), β = 95.870(2), γ = 115.7380(10), V = 945.1(2) ?3, and Z = 2. The central cobalt(II) atom is four-coordinated to nitrogen donors from two neutral abz ligands and two isothiocyanate
anions respectively, adopting a slightly distorted tetrahedral geometry. In addition, the intermolecular N–H···N and N–H···S
hydrogen bonds interactions link the discrete mononuclear units into infinite three-dimensional networks.
Index Abstract The essence sentence of the paper: In the mixed-ligand mononuclear complex, [Co(abz)2(SCN)2], the four coordinated cobalt(II) atom exhibits a slightly distort tetrahedron, which is further assembled into 3D infinite
network by intermolecular hydrogen interactions.

A novel metal-organic supramolecular complex [Zn2 (Zaltoprofen)2(phen)2] (where Zaltoprofen = 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid, phen = 1,10-phenanthroline) has been synthesized under hydrothermal condition and characterized by single crystal X-ray diffraction, elemental analysis, spectral method (IR), powder X-ray diffraction (XRD), electronic Spectra (UV-vis), and fluorescent properties. The compound crystallizes in the monoclinic P2(1)/c space group. [Zn2(Zaltoprofen)2(phen)2] features 0-D structural, the π–π stacking interactions and C?H···O hydrogen-bonds play a vital role in determining the crystal packing and construction of the extended 3-D supramolecular network. 相似文献

Abstract
The reaction of PdCl2 with a bulky acridine-based ligand afforded a novel PdII complex [Pd2(L)Cl4(CH3CN)](CH3CN)0.5 (1) (L = 9-[3-(2-pyridyl)pyrazol-1-yl]-acridine) exhibiting intra- and intermolecular C–H···Pd H-bonding interactions, which was characterized by elemental analysis, IR, and single-crystal X-ray diffraction analysis (triclinic system, space group P-1, with a = 8.774(6), b = 12.742(9), c = 14.149(10) ?, α = 67.573(11), β = 72.601(11), γ = 83.674(12)°, V = 1395.4(17) ?3, and Z = 2). Complex 1 has an asymmetrical dinuclear structure, which are further assembled into a one-dimensional (1D), and then two-dimensional (2D) network via intra- and/or inter-molecular C–H···Pd and C–H···Cl H-bonding interactions from different crystallographic directions. This work offers a new example in which the N donor of the acridine ring coordinates to a metal ion in a supramolecular coordination system. 相似文献5.

Abstract The title complex [Co2(bte)3(NCS)4(H2O)2]
n
(bte = 1,2-bis(triazol-1-yl)ethane) has been prepared. Single-crystal X-ray analysis reveals that the complex crystallizes
in space group P ī with a = 7.7962(2), b = 8.3407(4), c = 14.7735(5) ?, α = 86.835(2), β = 76.2031(9), γ = 80.583(3)°. The crystal consists of two discrete complexes, [Co(bte)(NCS)2(H2O)2] and [Co(bte)2(NCS)2]. The structure of [Co(bte)(NCS)2(H2O)2] consists of neutral chain containing Co(II) bridged by bte molecules. The six-co-ordination of Co2+ is achieved by means of two trans NCS− ions and water molecules. The structure of [Co(bte)2(NCS)2] demonstrates a one-dimensional neutral chain through bte-bridge, in which the Co(II) atom is in a distorted octahedral environment
formed by four nitrogen atoms of the triazoles and two nitrogen atoms from two trans thiocyanato liagnds.

Abstract A novel polymeric zinc(II) complex of quinine, [chlorosulphato (2-ethenyl)-4-azabicyclo[2.2.2]oct-5-ylium-(6-methoxyquinolin-4-yl)
methanol zinc(II)] has been synthesized and characterized. Single-crystal X-ray diffraction analysis of the complex (C20H25ClN2O6SZn) revealed that quinine forms a zigzag coordination polymeric complex with Zn(II) of extended chains –ZnCl–O–SO2–O–Zn–O–SO2–O–ZnCl–. The crystals are monoclinic, space group C2 with a = 20.5035(5), b = 9.7943(2), c = 11.7814(4) ?, β = 96.578(2)°, Z = 4, V = 2350.3(1) ?3. The complex exhibits a tetrahedral geometry. Each Zn(II) centre is thus coordinated to an O atom from each of two sulphate
bridges, a Cl atom and quinoline atom N(4) of the quinine moiety. The second quinuclidine nitrogen in the quinine is protonated.
In the crystal, there is linkage of two polymeric chains related by a twofold rotation axis, resulting in a bilayer. The linking
is achieved by hydrogen bonding from the quinine cation which provides two donors (–OH, N+–H), to oxygen atoms of sulphate groups which act as acceptors.

Abstract
A new Co(II) complex 2 with ligand 4,4,4-trifluoro-1-(6-methoxynaphthalen-2-yl) butane-1,3-dione 1 and pyridine are prepared and crystallized from an acetone solution. The obtained red and transparent crystal conforms to the empirical formula of Co(C15H10O3F3)2·(C5H5N)2. It crystallizes in monoclinic, space group C2/c with a = 23.3152(14), b = 12.0225(7), c = 15.3950(10) ?, β = 124.1360(10)°, V = 3571.8(4) ?3, Z = 4, C40H30CoF6N2O6, Mr = 807.59, F(000) = 1652, Dc = 1.502 g/cm3, μ = 0.564 mm−1, the final R = 0.0466 and wR = 0.1043 for 3901 observed reflections with I > 2σ(I). X-ray structural analysis revealed that the Co(II) atom is coordinated by two oxygen atoms of 1,3-dione ligands 1 and two nitrogen atoms of pyridines, forming a distorted octahedron coordination geometry. 相似文献18.

Abstract Two new complexes, [Cu(L)2(CH3OH)] · (ClO4)2 (1) and [Cu(L)2(H2O)] · (NO3)2 (2), have been synthesized and their crystal structures have been determined by X-ray analysis, where L = 3-(3,5-bimethylpyrazole-yl)-6-chloro-pyridazine].
The complex 1 crystallizes in the monoclinic, space group C2/c, and the coordination configuration of copper (II) is better described as trigonal pyramidal geometry with four N atoms from
L and one Omethanol. The coordination configuration of 2 is quite similar to that of 1 except Owater instead of Omethanol. The intermolecular hydrogen bonds link the repeat units and extend the molecules to multinuclear structures in both compounds.
The spectral properties of the title compounds have been studied and discussed. Furthermore, the antibacterial activities
of the title compounds have been detected, the results indicate that the ligands and two copper(II) complexes exhibit certain
fungicidal activities again several bacteria.
