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

The title compound, trans‐[RuIICl2(N1‐mepym)4] (mepym is 4‐methylpyrimidine, C5H6N2), obtained from the reaction of trans,cis,cis‐[RuIICl2(N1‐mepym)2(SbPh3)2] (Ph is phenyl) with excess mepym in ethanol, has fourfold crystallographic symmetry and has the four pyrimidine bases coordinated through N1 and arranged in a propeller‐like orientation. The Ru—N and Ru—Cl bond distances are 2.082 (2) and 2.400 (4) Å, respectively. The methyl group, and the N3 and Cl atoms are involved in intermolecular C—H?N and C—H?Cl hydrogen‐bond interactions. 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 complex cis‐[RuCl(DMSO)(phen)2]BPh4, where DMSO is dimethylsulfoxide and phen is 1, 10‐phenanthroline, crystallizes in the monoclinic space group P21/c with a = 19.505(4), b = 10.045(2), c = 21.199(4) Å, β = 90.137(4)°, V = 4153(2) Å3, Z = 4, Dcalc = 1.430 g cm—3. The ruthenium coordination geometry is that of a slightly distorted octahedron with a cis‐RuN4ClS arrangement of the ligand donor atoms. The Ru—Cl distance is 2.421(1) Å and the Ru—S distance 2.250(2) Å. The four Ru—N distances are 2.057(6), 2.066(4), 2.073(4), and 2.086(4) Å with the Ru—N bond trans to Cl the second shortest and the Ru—N bond trans to S the longest one. 相似文献

Five‐coordinate Cr(N)(salen) {salen is 2,2′‐[ethane‐1,2‐diylbis(nitrilomethylidyne)]diphenolate} reacts with [RhCl(COD)]2 (COD is 1,5‐cyclooctadiene) to yield the heterobimetallic nitride‐bridged title compound, namely chlorido‐2κCl‐[2(η4)‐1,5‐cyclooctadiene]{2,2′‐[ethane‐1,2‐diylbis(nitrilomethylidyne)]diphenolato‐1κ4O,N,N′,O′}‐μ‐nitrido‐1:2κ2N:N‐chromium(V)rhodium(I), [CrRh(C16H14N2O2)ClN(C8H12)]. The Cr—N bond of 1.5936 (14) Å is elongated by only 0.035 Å compared to the terminal Cr—N bond in the precursor. The nitride bridge is close to being linear [173.03 (9)°] and the Rh—N bond of 1.9594 (14) Å is very short for a monodentate nitrogen‐donor ligand, indicating significant π‐acceptor character of the Cr[triple‐bond]N group. 相似文献

Two different crystals (A and B) were used to structurally characterize trans‐[PtCl2(PPh3)2] and to study random and systematic errors in derived parameters. The compound is isomorphous with trans‐[PdCl2(PPh3)2] and with one of the polymorphs of trans‐[PtMeCl(PPh3)2] reported previously. Half‐normal probability plot analyses based on A and B show realistic s.u.'s and negligible systematic errors. R.m.s. calculations give very good agreement between A and B, 0.0088 Å. Important geometrical parameters are Pt—P = 2.3163 (11) Å, Pt—Cl = 2.2997 (11) Å, P—Pt—Cl = 87.88 (4) and 92.12 (4)°. Half‐normal probability plots and r.m.s. calculations were also used to compare the title compound with the palladium analogue, showing small systematic differences between the compounds. The torsion angles around the Pt—P bond were found to be very similar to those reported for isomorphous complexes, as well as to the torsion angles around the Pt—As bond in trans‐[PtCl2(AsPh3)2]. The NMR coupling constants for the title compound are similar to Pt—P coupling constants reported for analogous trans complexes. 相似文献

In the title compound, [RuCl2(C2H3N)(C27H31N3)]·0.5CH2Cl2, the RuII ion is six‐coordinated in a distorted octahedral arrangement, with the two Cl atoms located in the apical positions, and the pyridine (py) N atom, the two imino N atoms and the acetonitrile N atom located in the basal plane. The dichloromethane solvent molecule lies on a twofold axis. The two equatorial Ru—Nimino distances are almost equal (mean 2.089 Å) and are substantially longer than the equatorial Ru—Npy bond [1.914 (4) Å]. It is observed that the Nimino—M—Npy bond angle for the five‐membered chelate rings of pyridine‐2,6‐diimine complexes is inversely related to the magnitude of the M—Npy bond. The title structure is stabilized by intra‐ and intermolecular C—H⋯Cl hydrogen bonds. The intermolecular hydrogen bonds form an R66(24) ring and a chain of edge‐fused rings running parallel to the [001] direction. 相似文献

In the two ruthenium(II)–porphyrin–carbene complexes (dibenzoylcarbenyl‐κC)(pyridine‐κN)(5,10,15,20‐tetra‐p‐tolylporphyrinato‐κ4N)ruthenium(II), [Ru(C15H10O2)(C5H5N)(C48H36N4)], (I), and (pyridine‐κN)(5,10,15,20‐tetra‐p‐tolylporphyrinato‐κ4N)[bis(3‐trifluoromethylphenyl)carbenyl‐κC]ruthenium(II), [Ru(C15H8F6)(C5H5N)(C48H36N4)], (II), the pyridine ligand coordinates to the octahedral Ru atom trans with respect to the carbene ligand. The C(carbene)—Ru—N(pyridine) bonds in (I) coincide with a crystallographic twofold axis. The Ru—C bond lengths of 1.877 (8) and 1.868 (3) Å in (I) and (II), respectively, are slightly longer than those of other ruthenium(II)–porphyrin–carbene complexes, owing to the trans influence of the pyridine ligands. 相似文献

The title molecule is dimeric, i.e. di‐μ‐trimethylsiloxy‐bis(dichloroaluminium), [Al2Cl4(C3H9Si)2], and possesses exact crystallographic inversion symmetry. The O atoms of the trimethylsiloxy groups bridge the two Al atoms to form a four‐membered ring. The Si—O bond distance [1.711 (3) Å], the Al—O mean bond distance [1.806 (4) Å] and the mean Si—C bond distance [1.875 (6) Å] appear to agree well with standard data. Mean values for C—Si—C, O—Si—C, and Si—O—Al angles are 112.9 (3), 105.8 (2), and 131.8 (2)° repectively. The two ring angles O—Al—O and Al—O—Al are 84.43 (16) and 95.57 (16)°, respectively. 相似文献

The title compound, [Ru(C13H11N4S)2(C15H8N2)2], has C2 symmetry, with bidentate 2,2′‐bipyridyl ligands dictating a cis geometry around the RuII center. The monodentate S‐bonded dithizone ligands are almost planar, except for one of the phenyl rings, which is twisted by 34.2 (4)° from the N/N/C(S)/N/N plane. The Ru—S bond length is 2.4140 (13) Å, and the Ru—N bond lengths are 2.048 (4) and 2.074 (4) Å. 相似文献

The molecule of the title complex, [Rh(5‐NO2trop)(C18H15P)(CO)] (5‐NO2trop is 2‐hydroxy‐5‐nitrocyclohepta‐2,4,6‐trienone, C7H4NO4), has a distorted square‐planar geometry. Strong intramolecular and weak intermolecular hydrogen bonding is observed, with H⋯O distances of the order of 2.25 and 2.55 Å, respectively. The Rh—CO, Rh—O (trans to CO), Rh—O (trans to P) and Rh—P bond distances are 1.775 (7), 2.072 (4), 2.068 (4) and 2.2397 (17) Å, respectively, the O—Rh—O angle is 77.09 (16)° and the bidentate O—C—C—O torsion angle is 1.5 (7)°. 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 structures of tris(2‐methylquinolin‐8‐olato‐N,O)iron(III), [Fe(C10H8NO)3], (I), and aquabis(2‐methylquinolin‐8‐olato‐N,O)copper(II), [Cu(C10H8NO)2(H2O)], (II), have been determined. Compound (I) has a distorted octahedral configuration, in which the central Fe atom is coordinated by three N atoms and three O atoms from three 2‐methylquinolin‐8‐olate ligands. The three Fe—O bond distances are in the range 1.934 (2)–1.947 (2) Å, while the three Fe—N bond distances range from 2.204 (2) to 2.405 (2) Å. In compound (II), the central CuII atom and H2O group lie on the crystallographic twofold axis and the coordination geometry of the CuII atom is close to trigonal bipyramidal, with the three O atoms in the basal plane and the two N atoms in apical positions. The Cu—N bond length is 2.018 (5) Å. The Cu—O bond length in the basal positions is 1.991 (4) Å, while the Cu—O bond length in the apical position is 2.273 (6) Å. There is an intermolecular OW—H?O hydrogen bond which links the molecules into a linear chain along the b axis. 相似文献

The pendent‐arm macrocyclic hexaamine trans‐6,13‐dimethyl‐1,4,8,11‐tetraazacyclotetradecane‐6,13‐diamine (L) may coordinate in tetra‐, penta‐ or hexadentate modes, depending on the metal ion and the synthetic procedure. We report here the crystal structures of two pseudo‐octahedral cobalt(III) complexes of L, namely sodium trans‐cyano(trans‐6,13‐dimethyl‐1,4,8,11‐tetraazacyclotetradecane‐6,13‐diamine)cobalt(III) triperchlorate, Na[Co(CN)(C13H30N6)](ClO4)3 or Na{trans‐[CoL(CN)]}(ClO4)3, (I), where L is coordinated as a pentadentate ligand, and trans‐dicyano(trans‐6,13‐dimethyl‐1,4,8,11‐tetraazacyclotetradecane‐6,13‐diamine)cobalt(III) trans‐dicyano(trans‐6,13‐dimethyl‐1,4,8,11‐tetraazacyclotetradecane‐6,13‐diaminium)cobalt(III) tetraperchlorate tetrahydrate, [Co(CN)2(C14H32N6)][Co(CN)2(C14H30N6)](ClO4)4·4H2O or trans‐[CoL(CN)2]trans‐[Co(H2L)(CN)2](ClO4)4·4H2O, (II), where the ligand binds in a tetradentate mode, with the remaining coordination sites being filled by C‐bound cyano ligands. In (I), the secondary amine Co—N bond lengths lie within the range 1.944 (3)–1.969 (3) Å, while the trans influence of the cyano ligand lengthens the Co—N bond length of the coordinated primary amine [Co—N = 1.986 (3) Å]. The Co—CN bond length is 1.899 (3) Å. The complex cations in (II) are each located on centres of symmetry. The Co—N bond lengths in both cations are somewhat longer than in (I) and span a narrow range [1.972 (3)–1.982 (3) Å]. The two independent Co—CN bond lengths are similar [1.918 (4) and 1.926 (4) Å] but significantly longer than in the structure of (I), again a consequence of the trans influence of each cyano ligand. 相似文献

The title compound, [Ni(C7H5O3)2(C10H24N4)], contains octahedral NiII in a centrosymmetric trans configuration with Ni—N distances of 2.0637 (17) and 2.0699 (16) Å and an Ni—O distance of 2.1100 (14) Å. The molecules are linked by a single type of O—H?O hydrogen bond [O?O 2.618 (2) Å and O—H?O 161°] into two‐dimensional sheets; a singletype of N—H?O hydrogen bond [N?O 2.991 (2) Å and N—H?O 139°] links these sheets into a three‐dimensional framework. 相似文献

The complex has the classic three‐legged piano‐stool structure with a planar arene 1.667 Å from the metal, two monodentate O‐bound trifluoromethanesulfonate ligands [Ru—O 2.169 (2) and 2.174 (2) Å] and one N‐bound mesidine ligand [Ru—N 2.198 (2) Å]. The Ru—N distance is relatively long and the average Ru—O distance is relatively short when compared with previously characterized RuII complexes. 相似文献

The crystal structure of the title compound, [MnCl(C28H22N2O2)(C2H6O)], has been determined at 173 (2) K in the non‐centrosymmetric space group P212121. The asymmetric unit contains two molecular units. An intermolecular O—H⋯Cl hydrogen bond is formed between the OH group of an ethanol molecule coordinated to the Mn atom and the coordinated Cl− anion, and so polymeric chains of Mn‐containing fragments are formed [O—H⋯Cl = 3.1281 (16) and 3.1282 (15) Å]. The Mn atoms have a pseudo‐octahedral coordination sphere, with the four donor atoms of the Schiff base forming an equatorial plane [Mn—O distances are 1.8740 (13), 1.8717 (13), 1.8749 (13) and 1.8823 (13) Å, and Mn—N distances are 1.9868 (15), 1.9910 (14), 1.9828 (15) and 1.9979 (14) Å]. The axial positions are occupied by an ethanol molecule [Mn—O distances of 2.3069 (15) and 2.3130 (15) Å] and a Cl− ligand [Mn—Cl distances of 2.5732 (6) and 2.5509 (6) Å]. 相似文献
