In the title complex, [MnHg(SCN)4(C2H6SO)2]n, each Hg atom is tetrahedrally coordinated to four S atoms of the SCN ions, while each Mn atom is octahedrally coordinated to four N atoms of the SCN ions and two O atoms of the dimethyl sulfoxide molecules which occupy the trans positions. Each pair of Hg and Mn atoms is bridged by one SCN ion. Two Mn atoms, two Hg atoms and four SCN ions make a 16‐membered ring which organises into a two‐dimensional network. The dimethyl sulfoxide ligands are extended perpendicular to the plane on both sides. 相似文献

In the title coordination polymer, {[Ba(C8H5Cl2O3)2(H2O)]·H2O}n, each BaII atom is nine‐coordinated by six carboxylate O atoms and one ether O atom from five symmetry‐related 2,4‐dichlorophenoxyacetate ligands, and by two O atoms from water molecules, thus defining a distorted tricapped trigonal prism. The BaII ions are bridged by bidentate water molecules and by tridentate and tetradentate 2,4‐dichlorophenoxyacetate groups, leading to a two‐dimensional layer structure. The crystal structure is further stabilized by hydrogen‐bonding interactions within each layer. 相似文献

In the structure of the title complex, [Cu(C2O4)(C10H9N3)(H2O)]·H2O, the CuII atom displays a square‐pyramidal geometry, being coordinated by two N atoms from the di‐2‐pyridylamine ligand, two O atoms from the oxalate group and one O atom of a water molecule. The complex molecules are linked to form a three‐dimensional supramolecular array by hydrogen‐bonding interactions between coordinated/uncoordinated water molecules and the uncoordinated oxalate O atoms of neighboring molecules. 相似文献

The title compound, [Zn(C7H4NO4)2(C12H8N2)(H2O)], has been synthesized. X‐Ray analysis reveals that it is a neutral zinc(II) mononuclear carboxylate complex based on mixed N‐ and O‐donor ligands. The Zn atom is five‐coordinate in a distorted trigonal–bipyramidal coordination environment involving two O atoms of two monodentate 2‐nitrobenzoate molecules, two N atoms of a 1,10‐phenanthroline molecule and one O atom of a water molecule. The axial positions are occupied by a carboxylate O atom from the 2‐nitrobenzoate ligand and an N atom from the 1,10‐phenanthroline ligand [N—Zn—O = 167.66 (9)°]. 相似文献

In the title complex, {[MnHg(SCN)4(H2O)2]·2C4H9NO}n, each Mn atom is octahedrally coordinated to four equatorial thiocyanate N atoms and two axial water O atoms. The Mn atom and two O atoms lie on a twofold axis. Two kinds of crystallographically independent Hg atoms (denoted Hg1 and Hg2) are tetrahedrally coordinated with four thiocyanate S atoms and each Hg atom lies on a axis. N,N‐Dimethylacetamide molecules are connected to coordinated water molecules through hydrogen bonds. Each pair of Mn and Hg atoms is bridged via one thiocyanate ion. An Mn2Hg1Hg2(SCN)4 16‐membered ring is formed as a unit and the four metal atoms are in a chair‐form tetrahedral arrangement. The units are linked with one another and form infinite two‐dimensional networks. 相似文献

The title compound, [Ni(C3H10N2)2(H2O)2](C6H6NO3S)2, contains alternating layers of sulfanilate anions and diaquabis(1,3‐propanediamine)nickel(II) cations. The Ni atom lies on an inversion centre and is hexacoordinated by the 1,3‐propanediamine ligands, which function as N,N′‐bidentate ligands, and the water molecules, which are in a trans arrangement. The sulfanilate anions are arranged in layers, with the sulfonate and amine groups directed towards opposite sides of the layer. The structure is stabilized by a network of hydrogen bonding between the O and N atoms of the sulfanilate anions, the water molecules, and the N atoms of the 1,3‐propanediamine ligands. 相似文献

In the title compound, {[Zn(C10H8N2)(H2O)4](C6H5O4S)2·3H2O}n, the Zn atom, the bipyridine ligand and one of water molecules are located on twofold rotation axes. The Zn atom is coordinated by four O atoms from four water molecules and two N atoms from two 4,4′‐bipyridine molecules in a distorted octahedral geometry. The Zn2+ ions are linked by the 4,4′‐bipyridine molecules to form a one‐dimensional straight chain propagating along the c axis. The 4‐hydroxybenzenesulfonate counter‐ions are bridged by the solvent water molecules through hydrogen bonds to generate a two‐dimensional layer featuring large pores. In the crystal packing, the intralayer pores form one‐dimensional channels along the c axis, in which the one‐dimensional [Zn(C10H8N2)(H2O)4]2+ chains are encapsulated. Electrostatic interactions between cations and anions and extensive hydrogen bonds result in a three‐dimensional supramolecular structure. 相似文献

In catena‐poly[[[diaquanickel(II)]‐di‐μ‐glycine] dibromide], {[Ni(C2H5NO2)2(H2O)2]Br2}n, (I), the Ni atom is located on an inversion centre. In catena‐poly[[[tetraaquamagnesium(II)]‐μ‐glycine] dichloride], {[Mg(C2H5NO2)(H2O)4]Cl2}n, (II), the Mg atom and the non‐H atoms of the glycine molecule are located on a mirror plane. All other atoms are located on general positions. The atomic arrangements of both compounds are characterized by [MO6] octahedra (M = Ni or Mg) connected by glycine molecules, with the halogenide ions in the interstices. In (I), four of the coordinating O atoms are from glycine and two are from water molecules, building layers of octahedra and organic molecules. In (II), two of the coordinating O atoms are from glycine and four are from water molecules. The octahedra and organic molecules form chains. 相似文献

In the crystal structure of the title complex, [Zn(C3H2O4)(C12H8N2)(H2O)2], the ZnII atom displays a distorted octahedral geometry, being coordinated by two N atoms from the 1,10‐phenanthroline ligand, two O atoms from different carboxylate groups of the chelating malonate dianion and two O atoms of cis water molecules. The complex molecules are linked to form a three‐dimensional supramolecular array by both hydrogen‐bonding interactions between coordinated water molecules and the uncoordinated carboxylate O atoms of neighboring molecules, and aromatic π–π stacking interactions between neighboring phenanthroline rings. 相似文献

The title compound, [Zn(C7H8NO3S)2(H2O)4], has an octahedral coordination around the central Zn atom composed of two axial N atoms from the pyridine ligands and four equatorial O atoms of water molecules, forming a monomeric centrosymmetric complex. The two Zn—N bond distances are 2.102 (3) Å, while the four Zn—O bond distances range from 2.114 (2) to 2.167 (2) Å. Packing is determined by hydrogen bonds formed by the water molecules. The sulfonate group does not take part in coordination to the Zn atom. 相似文献

In the centrosymmetric title compound, [Co2(C12H10O2P)4(C5H5N)4(H2O)2], each approximately octahedral Co atom features two trans‐coordinated pyridine molecules, one water molecule, a terminally coordinated monodentate diphenylphosphinate ligand, and two bidentate diphenylphosphinate ligands that bridge the two Co atoms across a centre of inversion to form a dimeric binuclear complex. The discrete molecules are linked by double hydrogen bonds between the terminally coordinated diphenylphosphinate ligand and the water molecule to form a continuous chain along the crystallographic b axis. 相似文献

The stereoisomers of 7‐phenyl‐1‐oxa‐4‐thiaspiro[4.5]decan‐7‐ol, C14H18O2S, have the same stereochemistry at the C atom bearing an OH group, i.e. axial OH and equatorial phenyl groups. However, the acetal S and O atoms are axial and equatorial, respectively, in one isomer and reversed in the second. Furthermore, the crystals of one isomer are composed of hydrogen‐bonded molecules involving the hydroxyl H atom and the O atom of the five‐membered heterocyclic ring, with an O?O distance of 2.962 (3) Å, forming a polymeric chain along the b axis. The asymmetric unit of the other isomer is composed of two molecules, wherein hydroxyl H atoms and the O atoms of the five‐membered heterocyclic rings display intramolecular O—H?O hydrogen bonds with O?O separations of 2.820 (2) and 2.834 (2) Å. 相似文献

In the title compound, [Mn(C5H3N2O4)2(H2O)2], the MnII atom lies on an inversion centre, is trans‐coordinated by two N,O‐bidentate 1H‐imidazole‐4,5‐dicarboxylate monoanionic ligands [Mn—O = 2.202 (3) Å and Mn—N = 2.201 (4) Å] and two water molecules [Mn—O = 2.197 (4) Å], and exhibits a distorted octahedral geometry, with adjacent cis angles of 76.45 (13), 86.09 (13) and 89.20 (13)°. The complete solid‐state structure can be described as a three‐dimensional supramolecular framework, stabilized by extensive hydrogen‐bonding interactions involving the coordinated water molecules, the carboxy O atoms and the protonated imidazole N atoms of the imidazole‐4,5‐dicarboxylate ligands. 相似文献

In the title three‐dimensional coordination polymer, [Sr(4‐CPOA)(H2O)]n (where 4‐CPOA2− is the 4‐carboxylatophenoxyacetate dianion, C9H6O5), each SrII atom displays a bicapped triangular prismatic configuration, defined by five carboxyl and one ether O atom from five different 4‐CPOA2− ligands, as well as two water molecules. The SrII atoms are covalently linked by 4‐CPOA2− ligands and water molecules, giving rise to a three‐dimensional open framework. In previously studied polymers of this type, the 4‐CPOA2− ligand shows a variety of binding modes to metal ions, from mono‐ to pentadentate. In the present SrII complex, a novel hexadentate bridging mode is observed. 相似文献

The title compound, C34H26N4·2CH2Cl2, lies about an inversion center. The solvent molecules interact with the benzene molecule both through C—H⃛N hydrogen bonding to span pyridine N atoms of adjacent vinyl groups, possibly stabilizing the rotational conformation observed, and through a π interaction between a dichloromethane Cl atom and a pyridyl ring C—C bond of a c‐glide‐related molecule. The benzene molecules form stacks along the a axis such that two of the four olefin groups are properly oriented for photoreactivity (2+2 cyclodimerization). 相似文献

The title compound, [Sn(C5H5NS)2(C2H4S2)2], was obtained from a 1:2 mixture of bis(ethane‐1,2‐dithiolato)tin(IV) and 2‐mercaptopyridine. The molecules are discrete monomeric trans‐octahedral units, with the SnIV atom at the centre of symmetry, planar 2‐mercaptopyridine zwitterions and SnS2C2 groups in twist–envelope conformations. The 2‐mercaptopyridine ligands are monodentate and are bonded through the S atoms. The S—Sn distances between the S atom of edt (edt is ethane‐1,2‐dithiolate) and the Sn atom are 2.473 (1) and 2.505 (1) Å, which are slightly longer than the S—Sn distance in Sn(edt)2 of 2.390 (1) Å. The bond between the 2‐mercaptopyridine S atom and the Sn atom are, remarkably, weaker than the S—Sn bond involving edt. 相似文献

The title complex, [Cu(C11H14BrN2O)(NCS)]n, is an interesting thiocyanate‐bridged polynuclear copper(II) compound, which crystallizes with two independent molecules in the asymmetric unit. Each CuII atom is five‐coordinate in a square‐pyramidal configuration, with one O and two N atoms of one Schiff base ligand and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the apical position. The {4‐bromo‐2‐[2‐(dimethylamino)ethyliminomethyl]phenolato}copper(II) units are linked by the bridging thiocyanate ligands, forming polymeric chains running along the a axis. There are weak intermolecular C—H⋯O and C—H⋯S hydrogen bonds between the chains in the crystal structure. 相似文献
