A new triclinic polymorphic modification of the title compound, [Ag(C3H5OS2)(C18H15P)2], has been found and compared with the previously known orthorhombic modification [Tiekink (1988). Coord. Chem. 17 , 239–243]. The two polymorphs have the same molecular shape, viz. a distorted tetrahedral geometry, with a chelating dithiocarbonate (xanthate) and two PPh3 ligands bonded to the Ag atom. However, in this new polymorph, the xanthate ligand is bonded asymmetrically to the Ag atom, with Ag—S distances of 2.5489 (6) and 2.8055 (7) Å, while for the orthorhombic polymorph these distances are 2.686 (4) and 2.601 (4) Å. The Ag—P distances are similar in both structures. 相似文献

The structure of the title compound, [PtCl2(C5H5N)(C2H6S)], consists of discrete molecules in which the Pt‐atom coordination is slightly distorted square planar. The Cl atoms are trans to each other, with a Cl—Pt—Cl angle of 176.60 (7)°. The pyridine ligand is rotated 64.5 (2)° from the Pt square plane and one of the Pt—Cl bonds essentially bisects the C—S—C angle of the dimethyl sulfide ligand. In the crystal structure, there are extensive weak C—H⋯Cl interactions, the shortest of which connects molecules into centrosymmetric dimers. A comparison of the structural trans influence on Pt—S and Pt—N distances for PtS(CH3)2 and Pt(pyridine) fragments, respectively, in square‐planar PtII complexes is presented. 相似文献

The Ru—N bond distances in the title complex, [Ru(NO2)(C11H9N3)(C15H11N3)]BF4 or [Ru(NO2)(tpy)(azpy)]BF4, [tpy is 2,2′:6′,2′′‐terpyridine and azpy is 2‐(phenylazo)pyridine], are Ru—Npy 2.063 (4), Ru—Nazo 2.036 (4), Ru—Nnitro 2.066 (3) Å, and Ru—Ntpy 2.082 (4), 1.982 (3) and 2.074 (4) Å. The azo N atom is trans to the nitro group. The azo N=N bond length is 1.265 (5) Å, which is the shortest found in such complexes to date. This indicates a multiple bond between Ru and the N atom of the nitro group, and π‐backbonding [dπ(Ru) π*(azo)] is decreased. 相似文献

In the crystal structure of [Cu(CF3SO3)(C2N3)(C8H7N5)2]·0.5C2H6O, the CuII atom adopts a distorted octahedral geometry, with the basal plane formed by two N atoms of one dipyrimidinylamine ligand, one N atom of the second pyrimidine ligand and a nitrile N atom of the dicyanamide anion [Cu—N = 1.972 (2)–2.021 (2) Å]. The apical positions are occupied by an N atom of the second ligand [Cu—N = 2.208 (2) Å], and an O atom of the trifluoromethanesulfonate anion [Cu—O = 2.747 (2) Å] at a semi‐coordination distance. Pairs of inversion‐related N—H⋯N hydrogen bonds of the so‐called Watson–Crick type, augmented by two C—H⋯N contacts, link adjacent complexes into an infinite one‐dimensional chain running in the [101] direction. 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

In the first title salt, [Cu(C12H8N2)2(C5H10N2Se)](ClO4)2, the CuII centre occupies a distorted trigonal–bipyramidal environment defined by four N donors from two 1,10‐phenanthroline (phen) ligands and by the Se donor of a 1,3‐dimethylimidazolidine‐2‐selone ligand, with the equatorial plane defined by the Se and by two N donors from different phen ligands and the axial sites occupied by the two remaining N donors, one from each phen ligand. The Cu—N distances span the range 1.980 (10)–2.114 (11) Å and the Cu—Se distance is 2.491 (3) Å. Intermolecular π–π contacts between imidazolidine rings and the central rings of phen ligands generate chains of cations. In the second salt, [Cu(C10H8N2)2(C3H6N2S)](ClO4)2, the CuII centre occupies a similar distorted trigonal–bipyramidal environment comprising four N donors from two 2,2′‐bipyridyl (bipy) ligands and an S donor from an imidazolidine‐2‐thione ligand. The equatorial plane is defined by the S donor and two N donors from different bipy ligands. The Cu—N distances span the range 1.984 (6)–2.069 (7) Å and the Cu—S distance is 2.366 (3) Å. Intermolecular π–π contacts between imidazolidine and pyridyl rings form chains of cations. A major difference between the two structures is due to the presence in the second complex of two N—H...O hydrogen bonds linking the imidazolidine N—H hydrogen‐bond donors to perchlorate O‐atom acceptors. 相似文献

In the title compound, [Pd(C6H5)(C10H11O2S)(C18H15P)]·C4H8O, an isopropylthiobenzoate ligand is coordinated in a bidentate fashion to the central Pd atom through the O and S atoms. The square‐planar geometry of the Pd atom is completed by a phenyl ligand and a triphenylphosphine group but is distorted by the bidentate ligand, which forms a six‐membered chelate ring. This ring deviates strongly from planarity, which is illustrated by the plane through the phenyl portion of the chelate ring forming a dihedral angle of 62.3 (1)° with the coordination plane. 相似文献

In the title compound, [CuCl(C7H7O3S)(C12H8N2)(H2O)], the central Cu atom is coordinated by a water molecule, a chloride ion, an O‐monodentate p‐toluenesulfonate anion and an N,N′‐bidentate 1,10‐phenanthroline ligand. The copper environment is best described as a slightly distorted square pyramid, with bond distances Cu—Cl 2.2282 (9) Å, Cu—OW 1.984 (3) Å, and Cu—N 2.006 (3) and 2.028 (3) Å; the apical Cu—O distance is 2.281 (2) Å. In the supramolecular structure, π–π‐stacking stabilization is observed, and classical and non‐classical hydrogen bonds also play an important role. 相似文献

The crystal structure of the title compound, [CoCl‐(C16H26N6)]ClO4, consists of discrete [CoCl(C16H26N6)]+ cations and perchlorate anions. The five‐coordinate CoII atom has four nitrogen donors from the new mesocyclic ligand 1,5‐bis(1‐methyl‐1H‐imidazol‐2‐ylmethyl)‐1,5‐diazacyclooctane [Co—N 2.046 (3)–2.214 (4) Å], and a chloride anion at the apical site [Co—Cl 2.3184 (13) Å]. The coordination geometry of the complex is essentially square pyramidal. The mesocyclic ligand takes a boat–chair configuration and the two imidazole pendants are not coplanar. The dihedral angle between the two imidazole planes is 15.97°. An H atom from the 1,5‐diazacyclooctane group effectively blocks the axial coordination site opposite the Cl ligand. 相似文献

Molecules of the title compound, [PdCl(C6H4NO2S)(PPh3)2]·C3H6O, exhibit a slight distortion from exact planarity at the Pd atom towards tetrahedral, with P—Pd—P and Cl—Pd—S angles of 174.98 (3) and 174.19 (3)°, respectively. The Pd—Cl and Pd—S bonds are, respectively, long [2.3550 (11) Å] and short [2.3020 (12) Å] for their types; the S—C bond is also very short [1.744 (4) Å]. The solvating acetone molecule is linked to one of the phosphine ligands by means of a C—H?O hydrogen bond. 相似文献

In the title compound, [Co(C6H15N3)(C7H15N2S)]S2O6·H2O, the Co—C bond distance is 1.9930 (13) Å, which is shorter than for related compounds with the linear 1,6‐diamino‐3‐thiahexan‐4‐ide anion in place of the macrocyclic 1‐thia‐4,7‐diazacyclodecan‐8‐ide anion. The coordinated carbanion produces an elongation of 0.102 (7) Å of the Co—N bond to the 1,4,7‐triazacyclononane N atom in the trans position. This relatively small trans influence is presumably a result of the triamine ligand forming strong bonds to the CoIII atom. 相似文献

The title compound, [Cu(C2N3)(C12H8N2)2]ClO4, represents a relatively rare class of compounds with dicyanamide coordinated in a monodentate manner. The structure is formed by the [Cu{N(CN)2}(phen)2]+ complex cation (phen is 1,10‐phenanthroline) and an uncoordinated ClO4− anion. The Cu atom is five‐coordinate, with a slightly distorted trigonal–bipyramidal environment. The dicyanamide ligand is coordinated through one nitrile N atom in the equatorial plane, at a distance of 2.033 (6) Å from the metal. The two axial Cu—N distances are similar [mean 1.999 (4) Å] and are substantially shorter than the remaining two equatorial Cu—N bonds [mean 2.087 (1) Å]. 相似文献

The Re atom in [Re(C9H6N2)Cl3(C18H15P)] is octahedrally coordinated by three Cl atoms in facial positions, two N atoms from 8‐imidoquinoline (imq) and one P atom from triphenylphosphine. The Re—N(imido) distance [1.760 (9) and 1.772 (8) Å] for imq is very short and implies double‐bond character. The trans influence of the P atom is indicated. Intra‐ and intermolecular π–π interactions between the π‐rings in the complex are also observed. 相似文献

The crystal structure of the title compound, trans‐[Pd(NCS)2(C6H13N3P)2](NCS)2, is one of the few palladium(II) complexes containing two protonated water‐soluble 1,3,5‐triaza‐7‐phosphaadamantane (PTA) ligands reported to date. The compound displays a distorted square‐planar geometry, with the Pd atom on an inversion centre and with the S atoms of the thiocyanate counter‐ions occupying the axial positions above and below the equatorial plane described by the phosphine and thiocyanate ligands. Geometric parameters for the formal coordination polyhedron include a Pd—P distance of 2.2940 (8) Å, a Pd—S distance of 2.3509 (8) Å and a P—Pd—S angle of 89.45 (3)°. The effective cone angle for the PTA ligands was calculated as 114.5°. 相似文献
