The title complex, (C24H20P)2[WZnS4(S6)]·C3H6O or (Ph4P)2[WS2(μ‐S)2{Zn(S6)}]·Me2CO, was unexpectedly obtained on attempted recrystallization of a mixed tungten–zinc complex of a tris(pyrazolato)borate ligand. The two metal centres of the anion have distorted tetrahedral coordination and the two tetrahedra share one S...S edge; tungsten is additionally coordinated by two terminal sulfide ligands and zinc by a chelating S62− ligand, which has one central S—S bond significantly longer than the other four, a pattern found to be consistent for this ligand. This is the first reported example of a tetrahedral zinc centre bridging an edge of a single tetrathiotungstate(VI) or tetrathiomolybdate(VI) anion, although there are many previous examples with other metals. 相似文献

The title compound, (C24H24N7)2[Cd5Cl16(H2O)4]·H2O, contains a [Cd5Cl16(H2O)4]6− anion, two triply protonated tris[(1H‐benzimidazol‐3‐ium‐2‐yl)methyl]amine cations and one solvent water molecule. The structure of the anion is a novel chloride‐bridged pentanuclear cluster. The five unique CdII centres have quite different coordination environments. Two of the central hexacoordinated CdII cations have a CdOCl5 chromophore, in which each CdII cation is ligated by four bridging chloride ligands, one terminal chloride ligand and one water molecule, adopting a distorted octahedral environment. The third central CdII cation is octahedrally coordinated by four bridging chloride ligands and two water molecules. Finally, the two terminal CdII cations are pentacoordinated by two bridging and three terminal chloride ligands and adopt a trigonal–bipyramidal geometry. A three‐dimensional supramolecular network is formed through intra‐ and intermolecular O—H...O, O—H...Cl, N—H...Cl and N—H...O hydrogen bonds and π–π interactions between the cations and anions.<!?tpb=20.6pt> 相似文献

The title compound, [Cu2(SO4)2(C10H8N2)2(C2H6O2)2(H2O)2]n, contains two crystallographically unique CuII centres, each lying on a twofold axis and having a slightly distorted octahedral environment. One CuII centre is coordinated by two bridging 4,4′‐bipyridine (4,4′‐bipy) ligands, two sulfate anions and two aqua ligands. The second is surrounded by two 4,4′‐bipy N atoms and four O atoms, two from bridging sulfate anions and two from ethane‐1,2‐diol ligands. The sulfate anion bridges adjacent CuII centres, leading to the formation of linear ...Cu1–Cu2–Cu1–Cu2... chains. Adjacent chains are further bridged by 4,4′‐bipy ligands, which are also located on the twofold axis, resulting in a two‐dimensional layered polymer. In the crystal structure, extensive O—H...O hydrogen‐bonding interactions between water molecules, ethane‐1,2‐diol molecules and sulfate anions lead to the formation of a three‐dimensional supramolecular network structure. 相似文献

The asymmetric unit of the title two‐dimensional coordination polymer, {[Cd(C14H8O4)(C14H14N4)]·0.15H2O}n, is composed of one CdII cation, one biphenyl‐2,4′‐dicarboxylate (bpdc) anion, one 1,4‐bis(imidazol‐1‐ylmethyl)benzene (bix) ligand and 0.15 solvent water molecules. The coordination environment of the CdII cation is defined by four carboxylate O atoms from two different bpdc anions in a chelating mode and two N atoms from two distinct bix ligands, constructing a distorted trigonal prism polyhedron. Two inversion‐related CdII cations are bridged together by two positionally disordered bpdc anions, forming a 22‐membered ring with a Cd...Cd distance of 9.1966 (9) Å. These rings are then further linked by two bix ligands, extending into a two‐dimensional layer along (102) with 63 topology. 相似文献

Reactions of (Et4N)[Tp*WS3] [Tp* is hydridotris(3,5‐dimethylpyrazol‐1‐yl)borate] with CuSCN in MeCN in the presence of melamine afforded the title neutral dimeric cluster [Cu4W2(C15H22BN6)2(NCS)2S6(C2H3N)2] or [Tp*W(μ2‐S)2(μ3‐S)Cu(μ2‐SCN)(CuMeCN)]2, which has two butterfly‐shaped [Tp*WS3Cu2] cores bridged across a centre of inversion by two (CuSCN)− anions. The S atoms of the bridging thiocyanate ligands interact with the H atoms of the methyl groups of the Tp* units of a neighbouring dimer to form a C—H...S hydrogen‐bonded chain. The N atoms of the thiocyanate anions interact with the H atoms of the methyl groups of the Tp* units of neighbouring chains, affording a two‐dimensional hydrogen‐bonded network. 相似文献

The title compound, [Tb2(C24H12F9O6S3)2(C8H6N4)]·C4H8O2, has two terbium(III) centers bridged by the polyazine ligand 2,2′‐bipyrimidine (bpm), which is distorted from planarity by 7.0 (2)°. The terminal ligand 4,4,4‐trifluoro‐1‐(2‐thienyl)butane‐1,3‐dione (tta) is bidentate, coordinating through the two O atoms, while the bridging ligand is bis‐bidentate, coordinating through four equivalent N atoms. Both the complex and the ethyl acetate solvent molecules are disordered. The structure was refined as a non‐merohedral twin. 相似文献

The asymmetric unit of the title two‐dimensional coordination polymer, [Co2(C16H6O8)(C14H14N4)2]n, contains one Co2+ ion, half of a biphenyl‐3,3′,4,4′‐tetracarboxylate (bptc) anion lying about an inversion centre and one 1,4‐bis(imidazol‐1‐ylmethyl)benzene (bix) ligand. The CoII atom is coordinated by three carboxylate O atoms from two different bptc ligands and two N atoms from two bix ligands constructing a distorted square pyramid. Each Co2+ ion is interlinked by two bptc anions, while each bptc anion coordinates to four Co atoms as a hexadentate ligand so that four CoII atoms and four bptc anions afford a larger 38‐membered ring. These inorganic rings are further extended into a two‐dimensional undulated network in the (10) plane. Two CoII atoms in adjacent 38‐membered rings are joined together by pairs of bix ligands forming a 26‐membered [Co2(bix)2] ring that is penetrated by a bptc anion; these components share a common inversion centre. 相似文献

The title dicadmium compound, [Cd2(C10H8N2)5(H2O)6](C7H6NO2)2(ClO4)2·2H2O, is located around an inversion centre. Each CdII centre is coordinated by three N atoms from three different 4,4′‐bipyridine ligands and three O atoms from three coordinating water molecules in a distorted octahedral coordination environment. In the dicadmium cation unit, one 4,4′‐bipyridine (4,4′‐bipy) molecule acts as a bidentate bridging ligand between two Cd metal ions, while the other four 4,4′‐bipy molecules act only as monodentate terminal ligands, resulting in a rare `H‐type' [Cd2(C10H8N2)5(H2O)6] host unit. These host units are connected to each other viaπ–π stacking interactions, giving rise to a three‐dimensional supramolecular grid network with large cavities. The 3‐aminobenzoate anions, perchlorate anions and water molecules are encapsulated in the cavities by numerous hydrogen‐bonding interactions. To the best of our knowledge, this is the first example of a coordination compound based on both 4,4′‐bipyridine ligands together with discrete 3‐aminobenzoate anions. 相似文献

The title compound, [Cd(NCS)2(C13H10N4OS)2]n, contains SCN− anions acting as end‐to‐end bridging ligands which utilize both S and N atoms to link cadmium(II) centers into one‐dimensional double chains. The multidentate 5‐(4‐pyridyl)‐2‐(2‐pyridylmethylsulfanyl)‐1,3,4‐oxadiazole ligands behave as monodentate terminal ligands, binding metal centers only through the N atoms of the 4‐pyridyl groups. Two types of eight‐membered rings are formed by two SCN− anions bridging CdII centers, viz. planar and chair conformation, which are alternately disposed along the same chain. Finally, chains define a two‐dimensional array through two different interchain π–π stacking interactions. 相似文献

The title mononuclear [Cu(sq)(phen)2]·3H2O complex [sq is squarate (C4O4) and phen is 1,10‐phenanthroline (C12H8N2)] has been synthesized and the structure consists of a neutral mononuclear [Cu(sq)(phen)2] unit and three solvate water molecules. The CuII ion has distorted square‐pyramidal coordination geometry, comprised of one carboxylate O atom from a monodentate squarate ligand and four N atoms from two chelating phen ligands. An extensive three‐dimensional network of OW—H⋯O/OW hydrogen bonds, face‐to‐face π–π interactions between the 1,10‐phenanthroline aromatic rings and a weak π–ring interaction are responsible for crystal stabilization. 相似文献

Two Cl? anions bridge two CuII ions, each of which is also coordinated by two of the primary and the tertiary amino N atoms of the tren ligand, giving each metal atom a distorted square‐pyramidal coordination geometry. The cation lies about an inversion centre and the asymmetric unit also has two independent anions lying about inversion centres. 相似文献

In polymeric {[Eu(pzdc)(NO3)(phen)(H2O)]·H2O}n [pzdc is 2,3‐pyrazinedicarboxylate (C6H2O4) and phen is 1,10‐phenanthroline (C12H8N2)], each europium(III) ion is coordinated by seven O atoms (from three pzdc anions, a nitrate anion and a water molecule) and the two N atoms of the phen ligand, resulting in a nine‐coordinated europium(III) center with a distorted monocapped square‐antiprismatic coordination polyhedron. Four pzdc anions bridge four europium(III) ions, forming a parallelogram unit, the four vertices of which are occupied by the four pzdc anions. Moreover, each parallelogram unit links six other adjacent parallelogram units, forming a two‐dimensional network with disordered lattice water molecules. 相似文献

3‐(4‐carboxyphenyl)‐1‐methyltriazene N‐oxide reacts with KOH in methanol/pyridine to give {K[O2C‐C6H4‐N(H)NN(CH3)O]·4H2O}n, Potassium‐3‐(4‐carboxylatophenyl)‐1‐methyltriazene N‐oxide). The terminal carboxylato group of the anion does not interact with the cation. In the crystal lattice of {K(C8H8N3O3)·4H2O}n each three of the four water molecules interact with two potassium cations, every K+ ion being the centre of six bridging K···O interactions. Potassium cations interact further with the terminal N‐oxigen atom of single [C8H8N3O3]? anions achieving two parallel {C8H8N3O3?K+}n chains, which are linked through water molecules. The resulting polymeric, one‐dimensional chain, is operated by a screw axis 21 parallel to the crystallographic direction [010], along and equidistant to the K+ centres. The coordination of the K+ centres involves a distortion of the boat conformation of elementary sulfur (S8) with the ideal C2v symmetry. 相似文献

In the title coordination compound, [Zn(C12H6O4)(C14H14N4)]n, the two ZnII centers exhibit different coordination environments. One ZnII center is four‐coordinated in a distorted tetrahedral environment surrounded by two carboxylate O atoms from two different naphthalene‐1,4‐dicarboxylate (1,4‐ndc) anions and two N atoms from two distinct 1,4‐bis(imidazol‐1‐ylmethyl)benzene (1,4‐bix) ligands. The coordination of the second ZnII center comprises two N atoms from two different 1,4‐bix ligands and three carboxylate O atoms from two different 1,4‐ndc ligands in a highly distorted square‐pyramidal environment. The 1,4‐bix ligand and the 1,4‐ndc anion link adjacent ZnII centers into a two‐dimensional four‐connected (4,4) network. The two (4,4) networks are interpenetrated in a parallel mode. 相似文献

The molecule of the title compound {systematic name: di‐μ‐sulfido‐bis[diaqua(1,4,7,10,13,16‐hexaoxacyclooctadecane‐κ6O)barium(II)] bis[1,2‐benzisothiazol‐3(2H)‐one 1,1‐dioxide]}, [Ba2S2(C12H24O6)2(H2O)4](C7H5NO3S)2, lies on an inversion centre. The BaII atom encapsulated by the 18‐crown‐6 ring is coordinated by the six O atoms of the crown, two water O atoms and two bridging S atoms. The four‐membered ring composed of the BaII atoms and the bridging S atoms makes a dihedral angle of 67.1 (1)° with the crown‐ether ring. The aromatic ring system of the saccharin moiety is essentially planar. The packing is built up from layers of the molecules and is stabilized by three intermolecular O—H?O hydrogen bonds. 相似文献

In the title complex, [RuCl2(C7H7NO)(C2H6OS)2], the metal ion is at the centre of a distorted octahedral NOCl2S2 coordination sphere. The neutral 2‐acetylpyridine ligand binds to the metal ion through the pyridine N and carbonyl O atoms, forming a five‐membered chelate ring. The monodentate S‐coordinating dimethyl sulfoxide molecules are mutually cis, and the two remaining positions in the coordination sphere are occupied by two mutually trans Cl? ions. 相似文献

In the title compound, C15H13N2+·C24H20B−, the pyridyl ring of the cation makes a dihedral angle of 1.6° with the benzene ring. Each is rotated in the same direction with respect to the central –C—CH=CH—C– linkage, by 3.8 and 5.3°, respectively. The anions have a slightly distorted tetrahedral geometry. Molecular packing analysis was carried out using the packing energy portioning scheme in the program OPEC. Around each anion in the crystal structure there are eight anions, which interact with the central anion through C—H⋯π interactions. The cations are hydrogen bonded in a head‐to‐tail fashion, forming chains along [10]. 相似文献
