The title compound [Co(C5H7O2)2(C13H13P)(CH4O)]PF6·H2O, (I), which was converted from trans‐[Co(acac)2(PMePh2)(H2O)]PF6 (acac is pentane‐2,4‐dionato) by recrystallization from aqueous methanol, has been confirmed as have a coordinated methanol ligand. The molecular structure of the complex cation, trans‐[Co(acac)2(PMePh2)(MeOH)]+, is similar to that of the above aqua complex found in the ClO4 salt [Kashiwabara et al. (1995). Bull. Chem. Soc. Jpn, 68 , 883–888]. The Co—O bond length for the coordinated methanol is 2.059 (3) Å. There is an intermolecular hydrogen bond between the OH group of the coordinated methanol and one of the O atoms of the acac ligands in an adjacent complex cation [O5?O3′ = 2.914 (4) Å], giving a centrosymmetric dimeric dicationic complex. 相似文献

The two new title complexes, [Cu(N3)(dpyam)2]PF6 (dpyam is di‐2‐pyridylamine, C10H11N3), (I), and [Cu(N3)(dpyam)2]Cl·4H2O, (II), respectively, have been characterized by single‐crystal X‐ray diffraction. Both complexes display a distorted square‐pyramidal geometry. Each Cu atom is coordinated in the basal plane by three dpyam N atoms and one azide N atom in equatorial positions, and by another N atom from the dpyam group in the apical position. In complex (I), the one‐dimensional supramolecular architecture is assembled via hydrogen‐bonding interactions between the amine N atom and terminal azide N atoms and the F atoms of the PF6− anion. For complex (II), hydrogen‐bonding interactions between the amine N atom, the Cl− anion and water O atoms result in a two‐dimensional lattice. 相似文献

At 173 K, the dication of the title compound, C24H28Cl2N4Si2+·2I3?·CHCl3, is located on a crystallographic fourfold rotation axis. The chloro ligands occupy axial positions and the four 4‐methylpyridine ligands lie in the equatorial plane. The almost linear I3? ion is located on a crystallographic mirror plane and displays two significantly different I—I bond lengths. Furthermore, chloroform molecules, which are disordered about a centre of inversion, fill the remaining gaps in the crystal structure. 相似文献

The title compound, [Cu(O2CCH=CHCH3)2(C5H5N)2(H2O)], crystallizes as a monomer, with the copper ion in a pentacoordinated square‐pyramidal environment, bisected by a twofold axis passing through the metal atom and the apex. The molecules organise in chains connected by hydrogen bonds running along the unique b axis. 相似文献

In the title compound, azido‐2κN‐bis[μ‐(1η5:2κP)‐diphenylphosphinocyclopentadienyl][2(η5)‐pentamethylcyclopentadienyl]iron(III)rhodium(III) hexafluorophosphate, [{Rh(C10H15)(N3)}{Fe(μ‐C17H14P)2}]PF6 or [FeRh(C10H15)(μ‐C17H14P)2(N3)]PF6, the coordination sphere of RhIII can be described as pseudo‐tetrahedral, composed of two P atoms from a 1,1′‐bis(diphenylphosphino)ferrocene (dppf) ligand, an azido N atom and the centroid of the ring of a C5Me5 (Cp*) ligand. The two cyclopentadienyl rings in the dppf moiety adopt an eclipsed conformation. The Rh⋯Fe distance is 4.340 (2) Å. 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

The title compound was formed upon slow evaporation of a solution of the solvated dicationic complex bis(acetonitrile)bis[1,2‐bis(diphenyl‐phosphino)ethane]palladium(II) bis(tetrafluoroborate) in deuterated chloroform. The dinucleur palladium complex forms triclinic crystals and there is an inversion center between the Pd atoms. Compared to the corresponding monomeric compound, the Cl—Pd—Cl angles decrease upon briding from 94.19 (7) to 86.96 (4)°. 相似文献

The title compound, [Cu2(C14H23N5)2(CH3O)2](PF6)2, has a doubly methoxo‐bridged centrosymmetric copper dimer cation involving two tridentate bis(pyrazolyl)amine ligands. The geometry of each CuII atom is a distorted square pyramid with two N atoms of the pyrazole in bis[2‐(3,5‐dimethyl‐1‐pyrazolyl)ethyl]amine (bpea) and two μ2‐bridging O atoms of the methoxo ligands forming the basal plane, and the amine N atom occupying the axial position. In the bridging plane, the Cu—O bond lengths are 1.940 (4) and 1.942 (4) Å, and the bond angles for O—Cu—O and Cu—O—Cu are 76.1 (2) and 103.9 (2)°, respectively. The Cu?Cu distance is 3.058 (1) Å. The central four‐membered ring lies on an inversion centre. 相似文献

The crystal structure of the title compound, [Cu2(C2F3O2)2(C10H8N3O)2]·2CH3CN, contains discrete [Cu2(CF3COO)2(O‐dpa)2] molecules (O‐dpaH is di‐2‐pyridylamine 1‐oxide) which have imposed crystallographic twofold symmetry and an acetonitrile molecule of solvation. The O‐dpa− ligand is both bidentate and bridging, linking two Cu atoms with a separation of 3.4270 (11) Å. Each Cu atom is surrounded by four coordinated atoms that are almost coplanar, with dimensions Cu—N = 1.940 (2) and 1.984 (3) Å, and Cu—O = 1.912 (2) and 1.945 (2) Å. 相似文献

The title complex, [Ru(C2H3N)2(C6H6N2)(C18H15P)2](PF6)2.CH4O, is the third of a series of ruthenium complexes containing two triphenylphosphine groups in a trans arrangement, o‐benzoquinone diimine and two other non‐redox active ligands to been characterized. The effect of electron donor–acceptor properties of the two non‐redox active ligands does not change the quinone arrangement for the o‐benzoquinone diimine ligand, as can be seen from the bond distances of the quinone ring. The asymmetric unit contains half a molecule of complex cation (on a twofold rotation axis), one hexafluorophosphate anion and half a molecule of methanol in a general position close to a twofold rotation axis. 相似文献

The crystal structure of the title compound, [PtCl(CH3)(C18H33P)2], is isostructural with various platinum(II) and palladium(II) complexes containing two bulky tricyclohexylphosphine ligands in a trans orientation. The Pt atom resides on an inversion centre, resulting in a 50% statistical disorder in the chloro and methyl positions. The most significant geometrical parameters are Pt—P 2.3431 (8), Pt—Cl 2.440 (4) and Pt—C1 2.179 (13) Å, and P—Pt—P 180, P—Pt—Cl 89.15 (12) and 90.85 (12), and C—Pt—Cl 172.7 (5)°. The effective and Tolman cone angles for the tricyclohexylphosphine ligands were calculated as 160 and 162°, respectively. 相似文献

In the crystal structure of the title compound {systematic name: bis[6‐methyl‐1,2,3‐oxathiazin‐4(3H)‐one 2,2‐dioxide(1−)‐κ2N3,O4]bis(3‐methylpyridine)copper(II)}, [Cu(C4H4NO4S)2(C6H7N)2], the CuII centre resides on a centre of symmetry and has an octahedral geometry that is distorted both by the presence of four‐membered chelate rings and because of the Jahn–Teller effect. The equatorial plane is formed by the N atoms of two methylpyridine ligands and by the more basic O atoms of the acesulfamate ligands, while the weakly basic N atoms of these ligands are in elongated axial positions with a misdirected valence. The crystal is stabilized by two intermolecular C—H⋯O interactions involving the methyl and CH groups, and the sulfonyl O atoms of the acesulfamate group. 相似文献

The title compound, [Cu(C7H3O6S)2(C10H9N3)2][CuI(C10H9N3)2]2·2H2O, consists of anionic CuII moieties, cationic CuI species and uncoordinated water molecules. The anionic dimeric unit consists of one crystallographically independent fully deprotonated 5‐sulfosalicylate (2‐oxido‐5‐sulfonatobenzoate) anion, a di‐2‐pyridylamine group and a CuII atom. Each CuII atom is five‐coordinate within a square‐pyramidal geometry. The anion lies on a special position of site symmetry. In the cationic monomer, the CuI atom adopts tetrahedral geometry. The cations and anions are connected by O—H·O and N—H·O hydrogen bonds. 相似文献

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
