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

The title compound, (RS)‐3,5‐dichloro‐2‐{[(1‐phenylethyl)imino]methyl}phenol, C15H13Cl2NO, was synthesized from racemic 1‐phenylethylamine and 3,5‐dichlorosalicylaldehyde. The π‐conjugate system around the imine group is essentially planar in the phenol–imine tautomer. Intramolecular O⋯N hydrogen‐bond and intermolecular C—H⋯π interactions are present in the crystal structure. 相似文献

The title compound, [Ni(Ph2PCH2PPh2)2](ClO4)2, was synthesized and its structure determined crystallographically. The Ni atom lies on an inversion centre and is at the center of a square formed by four P atoms which are necessarily coplanar. The Ni—P distances are 2.2188 (5) and 2.2322 (5) Å, and the P—Ni—P angle is 73.12 (3)°. The unique perchlorate anion is not coordinated to the Ni atom. 相似文献

The crystal structure of the title compound, C9H6F3N, at 123 K contains molecules linked together via several C—H?F and C—H?N contacts, the strongest of which are 2.58 and 2.65 Å, respectively. Apparently, an F atom in the CF3 group is able to compete with a cyano N atom for aromatic H atoms but is less prone to interact with the more acidic methylene H atoms. The Ph–CH2CN torsion angle is ?6.4 (2)° and the planar phenyl ring exhibits a typical deformation of the endo angles at the ipso‐C atoms, due to the difference in the electron‐withdrawing power of the CF3 and CH2CN substituents. 相似文献

In the title compound, [Sn(C6H5)2(C12H19N2)]Br·H2O, the SnIV atom lies on a twofold axis and is coordinated by a C and two N atoms from the 2,6‐bis[(dimethylamino)methyl]phenyl ligand in a tridentate fashion and by two phenyl groups. The resulting geometry is intermediate between square pyramidal and trigonal bipyramidal, with three C atoms in equatorial and the two N atoms in axial positions. The main deformation from ideal trigonal‐bipyramidal geometry is seen for the N—Sn—N angle [152.18 (7)°]. The Br? anion and the water solvate molecule are on an inversion centre and twofold axis, respectively. They form an infinite chain of Br?H—O—H?Br hydrogen bonds [Br?O 3.529 (2) Å] without contributing to the primary coordination sphere of the Sn atom. 相似文献

In the title compound, [Cu(C5H10NO2S2)(C18H15P)2]·C18H15P, the Cu atom is in a distorted tetrahedral coordination, with two triphenylphosphine P atoms and two S atoms from an N,N‐bis(2‐hydroxyethyl)dithiocarbamate ligand occupying the vertices. The crystal structure is characterized by alternate layers of complex and triphenylphosphine molecules. 相似文献

The cation of the title compound, [Au4(PPh2CH2PPhCH2PPh2)2Cl2][Au(C6F5)3Cl]2 or [Au4Cl2(C32H29P3)2][AuCl(C6F5)3]2, displays a rhomboidal geometry for the Au atoms, with short Au?Au distances of 3.104 (2) and 3.185 (1) Å; the linear coordination at the AuI atoms is distorted: P—Au—P 164.7 (2)° and P—Au—Cl 170.67 (11)°. The anion shows the expected square‐planar geometry at AuIII, with the Au atom 0.022 (5) Å out of the plane of the four donor atoms. 相似文献

The cationic part of the homodifunctional aminophosphoranyl ligand, C41H41N2P2+·I?, shows interesting features associated with the N—P—C—P—N skeleton. The P—C(H) bond distances [1.696 (3) and 1.697 (3) Å] possess partial double‐bond characteristics. The nature of the P—C(H) and P—N bonds suggests that the positive charge is only distributed around the P—C—P atoms. The structure has near twofold symmetry through the central methylide‐C atom. 相似文献

The structures of a series of four‐coordinate nickel(II) complexes of the form [Ni(sacsac)L] PF6 (sacsac = pentane‐2,4‐dithione anion; L = (Ph2P)2(CH2)n, n = 1,2,3) have beendetermined. These are [bis(diphenylphosphino)methane](pentane‐2,4‐dithionato‐S,S′)nickel(II) hexafluorophosphate, [Ni(C25H22P2)(C5H7S2)]PF6, [1,2‐bis(diphenylphosphino)ethane](pentane‐2,4‐dithionato–S,S′)nickel(II) hexafluorophosphate, [Ni(C26H24P2)(C5H7S2)]PF6, and [1,3‐bis(diphenylphosphino)propane](pentane‐2,4‐dithionato‐S,S′)nickel(II) hexafluorophosphate, [Ni(C27H26P2)(C5H7S2)]PF6. All have a distorted square‐planar arrangement about Ni with angles around Ni varying with the length of the hydrocarbon chain. 相似文献

The title compound, C6H8NO+·H2PO4−, consists of 2‐(hydroxymethyl)pyridinium and dihydrogenphosphate ions. The dihydrogenphosphate moieties are linked into chains by pairs of P—O—H⃛O—P hydrogen bonds. The 2‐(hydroxymethyl)pyridinium cations are connected to the dihydrogenphosphate units by O—H⃛O and N—H⃛O hydrogen bonds. Weak π–π interactions help to determine the interchain packing. 相似文献

The molecule of the former title compound, C13H9ClN2O2, (I), is nearly planar, with an intramolecular O⋯O hydrogen bond of 2.692 (2) Å. The latter title compound, C17H18ClN3O4, (II), exists in the keto–amine tautomeric form, with a strong intramolecular hydrogen bond of 2.640 (2) Å between the O and N atoms, the H atom being bonded to the N atom. The azobenzene moieties of both molecules have trans configurations, and the dihedral angle between the planes of the two aromatic rings is 4.1 (1)° in (I) and 9.9 (1)° in (II). The N—H⋯O hydrogen‐bonded rings are almost planar and coupled with the cyclohexadiene rings in (II). 相似文献

The geometry about the Ru atom in the title compound, [Ru(C9H9N)2(C92H108N4O24)], is approximately tetragonal and the porphyrin ring is nearly planar, while the C—N—R angles [169.3 (3) and 163.9 (3)°] of the isocyanide ligands in the complex are different from the value of 180° expected in the free ligand. 相似文献
