The C—C distance in the dicarbollide cage is 1.649 (3) Å. 相似文献

The title compound, [CrSn(C6H5)3(C7H6NO2)3Cl][Sn(C6H5)3Cl(CH4O)], was obtained from the reaction of Ph3SnCl with the complex [Cr(C7H6NO2)3] in methanol. The structure contains [Ph3SnCl(MeOH)] (A) and [Ph3SnClCr(C7H6NO2)3] (B) molecules. In molecule A, the Sn atom of Ph3SnCl is coordinated by one methanol molecule. In molecule B, the Sn atom of Ph3SnCl is coordinated by one carboxylate O atom of [Cr(C7H6NO2)3]. Molecules A and B are connected through an O—H⋯O hydrogen bond between a carboxylate O atom and the methanol OH group. Weak C—H⋯Cl interactions and O—H⋯O hydrogen bonds extend the components of (I) into a two‐dimensional network. 相似文献

The asymmetric unit of the title complex, [PtCl2(C14H38B10P2)]·0.5CH2Cl2 or cis‐[PtCl2{1,2‐(PiPr2)2‐1,2‐C2B10H10}]·0.5CH2Cl2, contains one disordered solvent molecule and two molecules of the complex, in which each PtII atom displays slightly distorted square‐planar coordination geometry. The P atoms connected to the cage C atoms are coordinated to the PtII atom. The Pt—P distances vary slightly [2.215 (3) and 2.235 (4) Å] and the Pt—Cl distances are equal [2.348 (3) and 2.353 (5) Å]. 相似文献

The title compound, cis‐[Pd2Cl3(C7H7S)(C6H15P)2], has bridging chloro and arylthiolato groups, with the phosphines being trans to the bridging chloro group. The four‐membered metallocyclic Pd2ClS ring is unexpectedly non‐planar, with a dihedral angle of 133.8 (1)° between the PdCl2SP coordination planes. Principal dimensions include Pd—Clt 2.316 (3) and 2.329 (3), Pd—Clb 2.442 (3) and 2.432 (3), Pd—S 2.280 (3) and 2.282 (3), and Pd—P 2.233 (3) and 2.236 (3) Å (where Clt and Clb are terminal and bridging chloro ligands, respectively). 相似文献

The title compound, [Au2Cl2{Fe(C17H14P)2}], (I), contains the expected linear gold centres. The ferrocene moiety acts as a P,P′‐bridging ligand, wherein the Fe atom lies on an inversion centre. The P—Au—Cl angle is 177.56 (8)° and bond distances Au—P and Au—Cl are 2.2261 (18) and 2.2781 (18) Å, respectively. The structure is almost identical to that of the metal complex in (I)·2CH2Cl2 [Canales, Gimeno, Jones, Laguna & Sarroca (1997). Inorg. Chem. 36 , 5206–5211], but differs considerably from that in 3(I)·2CHCl3 [Hill, Girard, McCabe, Johnson, Stupik, Zhang, Reiff & Eggleston (1989). Inorg. Chem. 28 , 3529–3533], in that in the latter, the two independent molecules are linked by a short Au?Au contact. 相似文献

In the title compound, [Pd(CH3)2(C27H26P2)]·0.5C7H8, the Pd atom is at the centre of an approximately square‐planar arrangement of two P atoms and two methyl groups. The P—Pd—P angle [93.19 (3)°] is significantly larger than that in the corresponding dichloride complex [Pd(dppp)Cl2]. The toluene molecule is disordered across an inversion centre. 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

The reaction of ClAuPPh3 and 1,1′‐biphenyl‐2,2′‐dithiol in the presence of trimethylbenzylammonium chloride and K2CO3 in a tetrahydrofuran/methanol solution gives the title complex, [Au2(C12H8S2)(C18H15P)2]. The molecule contains P—Au—S units which `cross' with torsion angles of ∼90° [P—Au—Au—P = 86.23 (5)° and S—Au—Au—S = 95.62 (5)°]. The intra‐ and intermolecular Au⋯Au distances [3.9064 (3) and 6.3797 (5) Å, respectively] are outside the range for typical Au⋯Au interactions. However, the Au atoms appear to be drawn together, leading to a significant bending of the P—Au—S angles [170.24 (5) and 169.52 (5)°]. 相似文献

The title compound, [Ag3WIS4(C17H14NP)3]·0.5CH2Cl2, is a cubane‐type heterometallic cluster containing diphenyl(2‐pyridyl)phosphine (Ph2PPy). The pyridyl group of Ph2PPy remains uncoordinated, so the Ph2PPy ligand is monodentate and coordinates to one Ag atom. The W atom and three Ag atoms form a distorted tetrahedral geometry, capped by one I atom and three S atoms. 相似文献

In the title compound, [Au(C3H2N3S3)(C18H15P)3]·C3H7NO, the AuI atom has a distorted tetrahedral geometry consisting of one uncoordinated dimethylformamide molecule, one trithiocyanurate ligand and three PPh3 ligands. The S—Au distance is 2.909 (2) Å, and the P—Au distances fall in the range 2.400 (14)–2.4074 (13) Å. The S—Au—P angles are 92.81 (6), 99.17 (6) and 104.21 (5)°, and the P—Au—P angles are 114.46 (5), 119.04 (5) and 119.66 (5)°. 相似文献

The title compound, [Sn4(CH3)8(C13H8Cl2NO2)2(C2H5O)2O2], is a centrosymmetric dimer, with three linearly fused four‐membered Sn—O—Sn—O rings. The coordination polyhedron of the Sn atom bonded to the carboxylate can be described as trigonal–bipyramidal distorted toward square‐pyramidal. That of the second Sn atom is similar, but the distortion towards square‐pyramidal geometry is greater. The Sn—O and Sn—C distances are 2.020 (2)–2.226 (2) and 2.096 (4)–2.114 (4) Å, respectively. The benzene rings of the 2‐[(2,3‐dichlorophenyl)amino]benzoate ligand subtend an angle of 50.49 (17)°; the conformation of the ligand is stabilized by intramolecular N—H⋯Cl and N—H⋯O hydrogen bonds. The structure is assembled viaπ–π stacking interactions to form chains parallel to [10]. 相似文献

Tetraethylammonium 7‐dimethylsulfanyl‐nido‐dodecahydroundecaborate, [Et4N][7‐Me2S‐nido‐B11H12] or C8H20N+·C2H18B11S−, is a product of the deprotonation of [7‐Me2S‐nido‐B11H13] with KHBEt3 and precipitation with tetraethylammonium chloride. The effect of removing one endo‐terminal H atom is to cause a general contraction of the open‐face B—B distances. 相似文献

The title triangular tripalladium cluster, [Pd3Cl5(C18H15P)3]·C3H6O, (I), has a trigonal‐bipyramidal framework of Pd3(μ3‐Cl)2, with the two Cl atoms in apical positions. Each Pd atom in the framework has two additional coordination sites to establish square‐planar cis‐PdL2(μ3‐Cl)2 geometry. Three P atoms are located on the same side of the plane defined by the Pd3 triangle, which leads to a pseudo‐C3v symmetry for the core framework of Pd3(μ3‐Cl)2P3Cl3. The average Pd—Cl distance trans to PPh3 is 2.473 (8) Å, which is significantly longer than the average Pd—Cl distance of 2.294 (4) Å for those trans to terminal Cl, due to the strong trans effect of a P atom compared with a Cl atom. Compound (I) has 49 valence electrons and shows a rhombic electron‐spin resonance signal, indicating an S = ½ ground state. 相似文献

In the title compound, [Fe(C34H29O2P2)]2[Sb2Cl8], the discrete centrosymmetric [Sb2Cl8]2? anions are formed from two edge‐shared square pyramids of Cl atoms about each Sb atom. Within the cation, the two diphenylphosphinate groups share one H atom and the ferrocene cyclopentadienyl rings are in a staggered conformation, with the average value of the twist angle being 46°. In the crystal, each [Sb2Cl8]2? anion is involved in eight C—H?Cl interactions with four surrounding cations and these interactions interconnect the ions to form molecular columns along the a direction. 相似文献
