Abstract
The synthesis and crystal structure of the title organic charge-transfer salt (TTF)[Pt(mnt)2] (TTF = tetrathiafulvalene; mnt = cis-3,4-dimercapto-2-butenedinitrile) is described. The salt crystallizes in the P-1 space group with a = 7.9174(13) ?, b = 11.1583(18) ?, c = 11.2600(18) ?, α = 107.490(3)°, β = 91.631(3)°, and γ = 94.980(3)°. The stoichiometry between TTF and [Pt(mnt)2] is 1:1. The structure of (TTF)[Pt(mnt)2] consists of alternating stacks of dimerised TTF+ cations and dimerised [Pt(mnt)2]− anions, linked together by many kinds of short contacts and hydrogen bonds. Both the dimerised TTF+ cations and dimerised [Pt(mnt)2]− anions are arranged in a parallel face-to-face mode. 相似文献2.
Abstract
The synthesis and Crystal structure are given for the bis (N,N,N′,N′-tetramethylethylendiammonium) octaiodo pentachloroantimonate (III) salt. An X-ray investigation has shown that the title compound crystallizes in a monoclinic system, space group P21/m with the following lattice parameters a = 9.786(2) Ǻ, b = 14.024(5) Ǻ, c = 14.336(3) Ǻ, β = 91.35(2)° and Z = 2. The structure was solved from 3085 independent reflections with R 1 = 0.0402 and wR 2 = 0.0952 and refined with 152 parameters. The structure shows a layer arrangement perpendicular to the [(b)\vec] \vec{b} -axis: planes of [SbCl5]2−, I3 − and I5 − anions alternate with planes of [(CH2)2(NH(CH3)2)2]2+ cations. The [SbCl5]2− square pyramids present an active lone electron pair (LEP) on the Sb atoms and they are interconnected by means of N–H···Cl hydrogen bond originating from [(CH2)2(NH(CH3)2)2]2+ entities. The polyiodides (I3 − and I5 −) anions form a planer zigzag polymeric chains via I···I linking interactions. These chains are linked to the [SbCl5]2− anions by a long range contact. 相似文献3.
The mononuclear complex [Ni(DACH)2](H2O)2(CH3COO)2 (DACH = 1,4-diazacyclo-heptane) has been synthesized and characterized by IR, UV-Vis, elemental analysis and single crystal
X-ray diffraction. The complex crystallizes in monoclinic system, P21/n space group with a=7.500(3) ?, b=8.788(3) ?, c=16.429(6) ?, β=93.395(5)°, D

The title compound 2-(4,5-bis(4-methoxyphenyl)-5H-chromeno[4,3-b]pyridin-2-yl)- phenol (C32H25NO4, Mr = 487.53) was synthesized and crystallized. The crystal belongs to monoclinic, space group P2(1)/c with a = 12.4170 (11), b = 18.313 (2), c = 11.7103 (10) ?, β = 111.569(2)°, V = 2476.4(4) ?3, Mr = 487.53, Z = 4, Dc = 1.308 g/cm3, μ(MoK α ) = 0.086 mm−1, F(000) = 1024, the final R 1 = 0.0632 and wR 2 = 0.1454. X-ray analysis reveals that the atoms of C(1), C(2), C(3), C(4), C(5) and N(1) form a planar six-membered ring, while the atoms of C(1), C(2), C(6), C(7), C(12) and O(1) form a six-membered ring of envelope conformation. 相似文献5.

Abstract
The new hybrid material, cobalt selenate templated by 1,4-diazabicyclo[2.2.2]octane (abbreviated dabco), has been synthesised by the slow evaporation method at room temperature. Its crystal structure was investigated using single crystal X-ray diffraction data. It crystallises in the monoclinic system (space group P21/c) with the following unit-cell parameters: a = 12.9169(2) ?, b = 11.9101(2) ?, c = 12.4951(2) ?, β = 108.484(1)°, V = 1823.10(5) ?3 and Z = 4. The supramolecular structure of (C6H14N2)[Co(H2O)6](SeO4)2 consists of isolated [Co(H2O)]2+ and (C6H14N2)2+ cations and (SeO4)2− anions linked together by three dimensional hydrogen-bond network. The infrared spectroscopy confirmed the presence of these different entities. The thermal behaviour of the precursor, studied by thermodiffractometry and thermogravimetric analyses, indicates that its decomposition proceeds through three stages giving rise to the cobalt oxide. 相似文献7.
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8.

Abstract
The title compound, C17H13NO6, was synthesized and structurally characterized by elemental analysis, MS, 1H NMR and single crystal X-ray diffraction. It crystallizes in monoclinic system space group C 2/c with a = 27.981(6) ?, b = 12.996(3) ?, c = 8.0900(16) ?, β = 91.06(3)°, V = 2941.4(10) ?3, Z = 8, R 1 = 0.0675, wR 2 = 0.1626, and T = 298(2) K. The X-ray structure determination revealed that the center furanone ring is nearly coplanar with p-methoxybenzene ring and forms a dihedral angle of 87.2(1)° with the nitrobenzene ring. O–H···O Intermolecular hydrogen bonds link pairs of molecules into centrosymmetric dimers, making a graph set motif of R 22(10). The dimers are further assembled into a chain of edge-fused R 44(34) rings running along the [001] direction. The final three-dimensional supramolecular architecture is stabilized by weak π–π interactions. 相似文献9.

between the octaaquaoxalatodiiron cations and the isolated sulfate ions link the supramolecular complex into a quasi-three-dimensional
open-framework structure.

Abstract
A novel macrocyclic silver(I)-NHC complex was prepared by the quaternization reaction and anion metathesization reaction from 1-(1H-Imidazole-1-yl)methylene-1H-1,2,4-triazole as starting material. Its molecular structure was determined by single crystal X-ray diffraction and NMR spectroscopy, it crystallizes in triclinic space group P − 1 with a = 11.3286(10) ?, b = 11.4226(10) ?, c = 12.3987(12) ?, α = 79.0060(10)°, β = 82.1780(10)°, γ = 84.5930(10)°, V = 1556.5(2) ?3, z = 2. The silver ion was coordinated by the two carbene C atoms of two independent triazolylidene rings in linear geometry. A 20-membered macrometallacycle was formed through the bridged interaction between two silver ions and two carbene ligands. There are weak π–π interactions between two picrate anions or between picrate anion and triazolylidene ring. 相似文献13.

Abstract
4-Chlorobenzoic acid reacts with silver oxide and 1-(2-aminoethyl)piperidine to give a dinuclear silver(I) complex, [Ag2(C7H4ClO2)2(C7H16N2)2]. The complex was characterized by elemental analysis and X-ray diffraction. The complex crystallizes in the triclinic space group P−1 with unit cell dimensions a = 6.8550(10), b = 8.7370(10), c = 13.859(2) ?, α = 73.213(3), β = 87.945(3), γ = 77.050(3)°, V = 774.09(18) ?3, Z = 1, R 1 = 0.0386, and wR 2 = 0.0791. The dimeric Ag complex is located on an inversion center. The Ag atom in the complex is three-coordinated by two N atoms from two 1-(2-aminoethyl)piperidine ligands and by one O atom of a 4-chlorobenzoate ligand, forming a triangular coordination. In the crystal structure, the molecules are linked through intermolecular N–H···O hydrogen bonds, forming chains running along the a axis. The complex shows high cytotoxic property to both normal and carcinoma cells. 相似文献17.

Abstract
The cyclic di-amino acid peptide N,N′-diacetyl-cyclo(Gly-Gly), C8H10N2O4, crystallizes in the triclinic space group P[`1] P\bar{1} with unit cell parameters a = 9.4855(4) ?, b = 10.0250(3) ?, c = 10.0763(4) ?, α = 73.682(2)°, β = 82.816(2)°, γ = 81.733(2)°, V = 906.40(6) ?3, Z = 4 (2 molecules, A and B, per asymmetric unit), Dc = 1.452 g cm−3 and linear absorption coefficient 0.118 mm−1. The crystal structure determination was carried out with MoKα X-ray data measured at 120(2) K. In the final refinement cycle the data/restraints/parameter ratios were 4124/0/258 and goodness-of-fit on F2 = 1.0008. Final R indices for [I > 2σ(I)] were R1 = 0.0501, wR2 = 0.1007 and R indices (all data) R1 = 0.0864, wR2 = 0.11180. The largest electron density difference peak and hole were 0.241 and −0.232 e ?−3, respectively. The DKP rings in both molecules A and B have boat conformations with pseudo mm2 (C2v) symmetry if the N atoms and CH2 groups are considered identical. In each case, the prow and stern of the boat are the α-carbons C(3) and C(6). The overall molecular symmetry of molecules A and B is approximately C2 with the twofold symmetry axis of the DKP boat being maintained through the centre of the DKP ring. Details of the molecular geometry are compared with that of the parent compound cyclo(Gly-Gly) in which the DKP ring is planar with exact symmetry [`1] \bar{1} (Ci). 相似文献19.

Abstract
The reaction of [Ni(L)]Cl2·2H2O (L = 3.14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,01.18,07.12]docosane) with malonic (H2mal) acid yields a one-dimensional coordination polymer [Ni(L)(mal)2]n (1). The structure was characterized by X-ray crystallography, spectroscopic and magnetic susceptibility. Each nickel(II) ion has a distorted octahedral coordination environment with the four secondary amines of the macrocycle in which two carboxylate anions of the malonate ligand have assembled around each nickel center. The compound crystallizes in the monoclinic system C2/c with a = 19.487(4), b = 8.4143(12), c = 14.6036(18) ?, β = 102.232(11)°, V = 2340.2(6) ?3, Z = 4. Electronic spectrum of 1 exhibits a high-spin octahedral environment. The magnetic behavior of 1 reveals a weak intramolecular antiferromagnetic interaction with J values of −1.91(1) cm−1. 相似文献20.
