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 complex, di‐μ‐chloro‐bis[chloro(η6‐p‐cymene)ruthenium(II)]–9H‐carbazole (1/2), [Ru2Cl4(C10H14)2]·2C12H9N, is composed of one [RuCl2(η6‐p‐cymene)]2 and two 9H‐carbazole molecules. There are one‐half of a dinuclear complex and one 9H‐carbazole molecule per asymmetric unit. In the dinuclear complex, each of the two crystallographically equivalent Ru atoms is in a pseudo‐tetrahedral environment, coordinated by a terminal Cl atom, two bridging Cl atoms and the aromatic hydrocarbon, which is linked in a η6 manner; the Ru⋯Ru separation is 3.688 (3) Å. The title complex has a crystallographic centre of symmetry located at the mid‐point of the Ru⋯Ru line. Intermolecular N—H⋯Cl and π–π stacking interactions are observed. These interactions form a four‐pointed star‐shaped ring and one‐dimensional linear chains of edge‐fused rings running parallel to the [100] direction, which stabilize the crystal packing. 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

The title compound, [SnCl2(CH3)(C6H5)(C5H8N2)2], was obtained by reaction of dichloromethylphenyltin(IV) and 3,5‐dimethylpyrazole (dmpz) in chloroform, and was recrystallized from acetone. The structure consists of octahedral all‐trans [SnMePhCl2(dmpz)2] molecules, with the Sn atom coordinated to two C [Sn—C 2.127 (5) and 2.135 (4) Å], two Cl [Sn—Cl 2.5753 (8) Å] and two N atoms [Sn—N 2.357 (3) Å]. The dmpz ligands, bound to the metal through their unprotonated N atoms, form weak intra‐ and intermolecular hydrogen bonds with the Cl ligands via their NH groups, giving rise to a polymeric chain along the c axis. 相似文献

The adduct 1,6‐diaminohexane–1,1,1‐tris(4‐hydroxyphenyl)ethane (1/2) is a salt {hexane‐1,6‐diyldiammonium–4‐[1,1‐bis(4‐hydroxyphenyl)ethyl]phenolate (1/2)}, C6H18N22+·2C20H17O3?, in which the cation lies across a centre of inversion in space group P. The anions are linked by two short O—H?O hydrogen bonds [H?O 1.74 and 1.76 Å, O?O 2.5702 (12) and 2.5855 (12) Å, and O—H?O 168 and 169°] into a chain containing two types of R(24) ring. Each cation is linked to four different anion chains by three N—H?O hydrogen bonds [H?O 1.76–2.06 Å, N?O 2.6749 (14)–2.9159 (14) Å and N—H?O 156–172°]. In the adduct 2,2′‐bipyridyl–1,1,1‐tris(4‐hydroxyphenyl)ethane (1/2), C10H8N2·2C20H18O3, the neutral diamine lies across a centre of inversion in space group P21/n. The tris(phenol) molecules are linked by two O—H?O hydrogen bonds [H?O both 1.90 Å, O?O 2.7303 (14) and 2.7415 (15) Å, and O—H?O 173 and 176°] into sheets built from R(38) rings. Pairs of tris(phenol) sheets are linked via the diamine by means of a single O—H?N hydrogen bond [H?N 1.97 Å, O?N 2.7833 (16) Å and O—H?N 163°]. 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

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 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 novel title silver(I) coordination polymer, catena‐poly[[acetonitrilesilver(I)]‐di‐μ‐4‐[N‐(diphenylphosphino)aminomethyl]pyridine‐κ2N1:P;κ2P:N1‐[acetonitrilesilver(I)]‐μ3‐4‐[N,N‐bis(diphenylphosphino)aminomethyl]pyridine‐κ3N1:P:P′‐bis[acetonitrilesilver(I)(Ag—Ag)]‐μ3‐4‐[N,N‐bis(diphenylphosphino)aminomethyl]pyridine‐κ3P:P′:N1] tetrakis(tetrafluoroborate) acetonitrile trisolvate], {[Ag4(C2H3N)4(C18H17N2P)2(C30H26N2P2)2](BF4)4·3C2H3N}n, is formed by the self‐assembly of the Ph2P(4‐NHCH2C5H4N) and (Ph2P)2(4‐NCH2C5H4N) ligands with silver tetrafluoroborate. The polymer consists of alternating rings (which lie about inversion centers) bridged by the pyridyl rings of the bis‐phosphine‐substituted ligands, with anions hydrogen bonded the length of the chain. Two distinctly different metal coordination environments exist in the polymer, viz. distorted tetrahedral and trigonal geometries. 相似文献

The title compound, 3,4,5,6‐tetramethoxycyclohexane‐1,2‐diyldioxybis(methyldiphenylphosphonium) diiodide, C36H44O6P22+·2I?, was prepared from a New Zealand natural product, d ‐chiro‐inositol, in order to develop new catalytic metal complexes. The inositol ring retains its usual chair conformation with only minor perturbations caused by the bound diphenylmethylphosphines. Crystal‐packing forces are provided by C—H?I cation–anion interactions. 相似文献

In [Pt(dppe)(NO3)2], where dppe is ethylene-1,2-bis(diphenylphosphine) (C26H24P2), the Pt atom is coordinated by the two P atoms and by two O atoms of the two nitrate ions. The molecule has a distorted square-planar geometry, with one of the nitrate groups directed on each side of the plane. The cation in cis-[Pt(dppmO-O,P)2](NO3)2·2H2O, where dppmO is bis(diphenylphosphinomethyl)diphenylphosphine oxide (C25H22OP2), comprises two five-membered chelate rings, each dppmO ligand being coordinated to platinum through one P atom and the O atom. The larger P—Pt—P angle of 102.25 (4)° is due to steric interactions between the two phenyl groups on each P atom. 相似文献
