Diphenyl (p-tolylamido)phosphate
The P atom in the title compound, C(19)H(18)NO(3)P, exhibits a distorted tetra-hedral configuration while the N atom shows a planar coordination. In the crystal, inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers.

We study the pion-nucleon P33 and P11 scattering, where the Delta and the Roper resonances are seen, respectively. We use the Lippmann-Schwinger equation extended to couple to a one-body state, and investigate nature of these resonances by taking and omitting a one-baryon state into account. We see validity and puzzle of the standard quark model interpretation, for the Delta and the Roper reson...
متن کاملP,P-Diphenyl-N-(1,1,2,2-tetraphenyl-1λ5-diphosphanylidene)phosphinous amide
The title compound, C(36)H(30)NP(3), a structural isomer of tris-(diphenyl-phosphino)amine, was unexpectedly isolated as the sole phospho-rus-containing product from the reaction of Mg[N(PPh(2))(2)](2)(THF)(2) (THF is tetra-hydro-furan) with CO(2). Its identity was confirmed by (31)P NMR spectroscopy and single-crystal X-ray diffraction. The geometry at the two P(III) atoms is trigonal pyramida...
متن کامل1,1′-Diphenyl-3,3′-(p-phenylenedicarbonyl)dithiourea
The mol-ecule of the title compound, C(22)H(18)N(4)O(2)S(2), lies across a crystallographic inversion centre. The central benzene ring forms dihedral angles of 29.39 (9) and 79.11 (12)°, respectively, with the thio-urea unit and the terminal phenyl ring. Intra-molecular N-H⋯O hydrogen bonds generate two S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [10] by inter-mole...

The title compound, C62H78N4P4Se2Si4·2C5H12, is made up of two [SeC(PPh2NSiMe3)(PPh2NHSiMe3)] units related by an inversion center situated at the mid-point of the diselenide bond. It crystallized with two disordered mol-ecules of pentane used as solvent of crystallization. It is a rare example of an anti-periplanar diselenide and exhibits a long Se-Se bond of 2.4717 (8) Å. The Se-C bond length...
