In the title compound, [(Ph(3)P)(2)N](+)·[Cl-H-Cl](-) or C(36)H(30)NP(2) (+)·Cl(2)H(-), the H atom of the [Cl-H-Cl](-) anion and the N atom of the [(Ph(3)P)(2)N](+) cation are located on a twofold axis, yielding overall symmetry 2 for both the cation and the anion. The central P-N-P angle [144.12 (13)°] of the cation is in the expected range and indicates only weak cation-anion inter-actions. T...
In the title mol-ecule, C(27)H(19)FN(2), the imidazole ring is essentially planar [maximum deviation = 0.004 (1) Å] and makes dihedral angles of 62.80 (6), 36.98 (6), 33.16 (6) and 46.24 (6)°, respectively, with the substituent rings in the 1-, 2-, 4- and 5-positions. No classical hydrogen bonds are observed in the crystal structure.
The dioxaphospho-lane ring in the title compound, C(20)H(17)O(3)P, adopts an envelope conformation about one of the ring carbons. The benzene rings of the compound do not form face-to-face π-π inter-actions, instead weak C-H⋯π inter-actions occur between adjacent mol-ecules. The methine H atoms on the dioxaphospho-lane ring form weak C-H⋯O hydrogen bonds to the oxide group of an adjacent mol-ec...
In the title mol-ecule, C(23)H(20)N(2), the heterocyclic ring adopts a screw-boat conformation, with all substituents equatorial. The phenyl ring at position 3 makes dihedral angles of 78.12 (15) and 72.67 (15)°, respectively, with the phenyl rings at positions 5 and 6; the dihedral angle between the phenyl rings at positions 5 and 6 is 67.32 (14)°. A C-H⋯π inter-action is present in the crysta...
In the title salt, C(19)H(15)N(4) (+)·C(24)H(20)B(-), the tetra-phenyl-borate anion is in a tetra-hedral geometry around the B atom [C-B-C angles of 107.10 (9)-111.79 (9)°]. In the cation, the tetra-zole ring makes dihedral angles of 3.04 (7), 51.75 (7) and 51.13 (7)° with the attached phenyl rings. In the crystal, C-H⋯π inter-actions link the cations and anions into ion pairs.
Colourless needle-shaped crystals of the title compound, (C(26)H(21)BrOP)(2)[Hg(2)Br(6)], have been prepared by addition of a solution of HgBr(2) in methanol to a solution of (4-bromo-benzoyl-meth-yl)triphenyl-phospho-rane in dry methanol. The compound features Hg(2)Br(6) (2-) dianions, whose site symmetry is .
The title compound, [Sb(2)(C(6)H(5))(6)(CH(3)O)(2)O]·2CH(3)OH, is the methanol disolvate of a dinuclear triphenyl-anti-mony derivative. The mol-ecule shows C(s) symmetry. The Sb-O-Sb angles cover a range from 89.65 (10)° to 102.08 (13)°. In the crystal structure, two O-H⋯O hydrogen bonds are present.
Monodisperse, size-controlled Ni-P nanoparticles were synthesised in a single step process using triphenyl-phosphane (TPP), oleylamine (OA), and Ni(II)acetyl-acetonate. The nanoparticles were amorphous, contained ~30 at% P and their size was controlled between 7-21 nm simply by varying the amount of TPP. They are catalytically active for tailored carbon nanotube growth.
The title compound, [Ni(C(14)H(9))Cl(C(18)H(15)P)(2)], was synthesized from the reaction between 9-chloro-phenanthrene, NiCl(2)·6H(2)O and triphenyl-phosphane in ethanol. The bond angles around the Ni(II) atom indicate that it exists in a slightly distorted square-planar geometry.
