The trichloro‐bridged dinuclear RuII complex tri‐μ‐chloro‐bis{[1,1,1‐tris(diphenylphosphinomethyl)ethane‐κ3P,P′,P′′]ruthenium(II)} hexafluorophosphate ethanol solvate, [Ru2Cl3(tripod)2]PF6·C2H6O, containing the tripod [1,1,1‐tris(diphenylphosphinomethyl)ethane, C41H39P3] ligand, was unexpectedly obtained from the reaction of [RuIIICl3(tripod)] with 1,4‐bis(diphenylphosphino)butane (dppb), followed by precipitation with NH4PF6. The magnetic moment of the compound at room temperature indicates that the dinuclear [Ru2(μ‐Cl)3(tripod)2]+ cation is diamagnetic. A single‐crystal X‐ray structure determination revealed that the two Ru atoms are bridged by the three Cl atoms. The coordination sphere of each Ru atom is completed by the three P atoms of a tripod ligand. The two P3Ru units are exactly eclipsed, while the bridging Cl atoms are staggered with respect to the six P atoms. The Ru⋯Ru distance is 3.3997 (7) Å and the mean Cl—Ru—Cl bond angle is 77.7°. 相似文献

The tetradentate N2S2 Schiff base ligand 3,3′‐[2,2′‐(ethylenedioxy)dibenzylidene]bis(S‐methyl dithiocarbazate) (H2L), prepared by the condensation of S‐methyl dithiocarbazate with 1,4‐bis(2‐formylphenyl)‐1,4‐dioxabutane in a 1:2 molar ratio, reacts with nickel acetate to form the title neutral metal complex, [Ni(C20H20N4O2S4)]. The X‐ray structure of the complex shows a distorted square‐planar geometry around the Ni atom. The monomeric units are weakly associated into dimers via a long Ni?S interaction [3.569 (1) Å]. These dimeric units are then linked by C—H?S intermolecular contacts to form a polymeric chain along the a axis. 相似文献

The crystal structure consists of neutral complexes of [ReOCl3(dppp)] [dppp is 1,3‐bis(diphenylphosphino)propane] packed by H?π‐ring interactions. The Re atom is octahedrally coordinated to the oxo anion, three Cl atoms and two P atoms from the dppp ligand. The six‐membered ring formed by the bidentate dppp ligand and the rhenium metal centre is in a chair conformation. The title compound is an intermediate in the synthesis of bis(dppp) complexes of rhenium. 相似文献

Gold(I) cyanide forms complexes with imidazolidine‐2‐thione (etu) and dimethylthiourea (dmtu) with the formula [Au2(CN)2L2], i.e. the title complexes dicyano‐1κC,2κC‐bis(imidazolidine‐2‐thione)‐1κS,2κS‐digold(I)(Au—Au), [Au2(CN)2(C3H6N2S)2], and dicyano‐1κ2C‐bis(N,N′‐dimethylthiourea)‐2κ2S‐digold(I)(Au—Au), [Au2(CN)2(C3H8N2S)2]. In the etu complex, two approximately linear (etu)AuCN groups are held together by a weak homopolar Au—Au bond [3.117 (1) Å], with a torsion angle of 61 (3)° between the two groups. In the dmtu complex, an approximately linear Au(dmtu)2 group is bound to an approximately linear Au(CN)2 group by a weak heteropolar Au—Au bond [3.091 (1) Å], with a torsion angle of 83 (5)° between the two groups. 相似文献

The absolute configuration of the title compound, alternatively called (+)‐(4,5‐dihydro‐2,5‐diphenyloxazol‐4‐yl)methanol, C16H15NO2, has been confirmed as 4S,5S. The hydroxymethyl group and phenyl ring at the asymmetric C atoms exhibit β and α orientations, respectively. The exocyclic C—C bonds at the asymmetric C atoms are mutually anticlinal (?ac). The hydroxyl group and the N atom of the oxazoline ring are involved in an intermolecular hydrogen bond leading to chains of molecules. 相似文献

In the title two‐dimensional coordination polymer, [Mn(1,4‐BDOA)(4,4‐bipy)(H2O)2]n [1,4‐BDOA2− is the p‐phenylenedioxydiacetate dianion (C10H8O6) and 4,4‐bipy is 4,4‐bipyridine (C10H8N2)], each MnII atom displays octahedral coordination by two O atoms of the 1,4‐BDOA2− groups, two N atoms of the 4,4‐bipy ligands and two solvent water molecules. The MnII atom, 4,4‐bipy ligand and 1,4‐BDOA2− group occupy different inversion centres. Adjacent MnII atoms are bridged by 1,4‐BDOA2− groups and 4,4‐bipy ligands, forming a two‐dimensional network with Mn⋯Mn separations of 11.592 (2) and 11.699 (2) Å. Hydrogen bonds from a water O—H group link the layers in the third dimension. 相似文献

In order to model processes of chemisorption in organic salts formed between dinitrobenzoic acids (DNBH) and secondary amines (R2NH), a series of compounds of composition [MII(3,5‐DNB)2(DMSO)2(H2O)2] (where MII is Zn, Cu, Ni or Co, 3,5‐DNB is the 3,5‐dinitrobenzoate ion, and DMSO is dimethyl sulfoxide) have been prepared. In diaquabis(dimethyl sulfoxide)bis(3,5‐DNB)zinc(II), [Zn(C7H3N2O6)2(C2H6OS)2(H2O)2], the 3,5‐DNB ions and molecules of DMSO are monodentate ligands that are coordinated to the Zn atom through their O atoms. These ligands, together with two molecules of water, form a slightly distorted octahedral coordination environment for the Zn atom, which lies on a center of symmetry. 相似文献

In ferrocene‐1,1′‐diylbis(diphenylmethanol)–4,4′‐ethylenedipyridine (1/1), [Fe(C18H15O)2]·C12H12N2, there is an intramolecular O—H?O hydrogen bond in the ferrocenediol component and a single O—H?N hydrogen bond linking the two components into a finite monomeric adduct. Ferrocene‐1,1′‐diylbis(diphenylmethanol)–ethylenediamine (1/1), [Fe(C18H15O)2]·C2H8N2, crystallizes with Z′ = 2 in space group P, and there are two independent four‐component aggregates in the structure, both of which are centrosymmetric. In the first type of aggregate, the molecular components are linked by O—H?N and N—H?O hydrogen bonds, in which both diamine N atoms participate; in the second type of aggregate, the diamine component is disordered over two sets of sites, but only one N atom is involved in the hydrogen bonding. 相似文献

In the adduct ferrocene‐1,1′‐diylbis(diphenylmethanol)–1,2‐bis(4‐pyridyl)ethene (1/1), [Fe(C18H15O)2]·C12H10N2, there is an intramolecular O—H?O hydrogen bond in the ferrocenediol component and a single O—H?N hydrogen bond linking the diol to the diamine, which is disordered over two sets of sites, so forming a finite monomeric adduct. In the adduct ferrocene‐1,1′‐diylbis(diphenylmethanol)–1,6‐diaminohexane (2/1), 2[Fe(C18H15O)2]·C6H16N2, the amine lies across a centre of inversion in space group P. There is an intramolecular O—H?O hydrogen bond in the ferrocenediol, and the molecular components are linked by O—H?N and N—H?O hydrogen bonds, one of each type, into a C(13)[R(12)] chain of rings. 相似文献

The reaction of cadmium chloride with pyridine‐2,6‐dicarboxylic acid (PDA) and 98% H2SO4 in ethanol led to the formation of the title compound, bis[μ‐6‐(ethoxycarbonyl)pyridine‐2‐carboxylato]‐1:2κ4O6,N,O2:O2;1:2κ4O2:O2,N,O6‐bis[diaquachlorocadmium(II)] dihydrate, [Cd2(C9H8NO4)2Cl2(H2O)4]·2H2O. PDA is esterified to monoethyl pyridine‐2,6‐dicarboxylate (MEPD) by the catalysis of H2SO4 during the reaction. The dinuclear CdII complex lies about an inversion centre and the unique Cd atom has a pentagonal–bipyramidal geometry. The two Cd atoms are bridged by two carboxylate O atoms, forming a planar Cd2O2 unit. Stair‐like chains are formed via O—H⋯Cl hydrogen bonds and these are further arranged into two‐dimensional layers via hydrogen bonds involving solvate water molecules. 相似文献

The syntheses and structures of two mixed‐ligand complexes of platinum(II) with deprotonated oxopurine bases and triphenylphosphine are reported, namely the theophyllinate complex cis‐bis(1,2,3,6‐tetrahydro‐1,3‐dimethylpurine‐2,6‐dionato‐κN7)bis(triphenylphosphine‐κP)platinum(II), [Pt(C7H7N4O2)2(C18H15P)2], (I), and the theobrominate complex cis‐chloro(1,2,3,6‐tetrahydro‐3,7‐dimethylpurine‐2,6‐dionato‐κN1)bis(triphenylphosphine‐κP)platinum(II) ethanol hemisolvate, [PtCl(C7H7N4O2)(C18H15P)2]·0.5C2H5OH, (II). In (I), the coordination geometry of Pt is square planar, formed by the two coordinating N atoms of the theophyllinate anions in a cis arrangement and two P atoms from the triphenylphosphine groups. In (II), there are two crystallographically independent molecules. They both exhibit a square‐planar coordination geometry around Pt involving one Cl atom, the coordinating N atom of the theobrominate anion and two P atoms from the triphenylphosphine groups. The two triphenylphosphine groups are arranged in a cis configuration in both structures. The heterocyclic rings are rotated with respect to the coordination plane of the metal by 82.99 (8) and 88.09 (8)° in complex (I), and by 85.91 (16) and 88.14 (18)° in complex (II). Both structures are stabilized by intramolecular stacking interactions involving the purine rings and the phenyl rings of adjacent triphenylphosphine moieties. 相似文献

In the cation of the title complex, cis,cis,cis‐[Ru(η2‐O2CMe)(dppe)2]PF6·2MeOH [dppe is 1,2‐bis(diphenylphosphino)ethane, C26H24P2], the Ru atom is in a pseudo‐octahedral coordination environment with two chelating dppe ligands and one chelating acetate ligand. Intra‐phosphine and intra‐acetate bond lengths and angles are unexceptional. Deviations from idealized octahedral coordination angles at ruthenium [O—Ru—O 59.43 (8)° and P—Ru—P 103.19 (2)°] presumably derive from constraints imposed by the chelate rings. The Ru—P distances for the mutually trans P‐donor atoms [2.3785 (6) Å] are significantly longer than those for the Ru—P linkages trans to the acetate ligand [2.3074 (6) Å]. The Ru1, C1 and C2 atoms lie on a twofold axis, and atom P3 of the anion lies on an inversion centre. 相似文献
