Tri-p-tolylphosphine
In the title compound C(21)H(21)P, the P atom is situated on a crystallographic threefold rotatory-inversion axis, resulting in threefold rotation symmetry of the title compound. The dihedral angles between the symmetry-related benzene rings are 87.40 (18)°.
متن کامل2,4,6-Tri-p-tolylpyridine
In the title compound, C(26)H(23)N, the complete molecule is generated by crystallographic mirror symmetry, with the N atom and four C atoms lying on the reflection plane. The dihedral angles between the pyridine ring and pendant benzene rings are 2.9 (1), 14.1 (1) and 14.1 (1)°. Neighbouring mol-ecules are stabilized through inter-molecular π-π inter-actions along the c axis [centroid-to-centr...
متن کاملHippokrates Ueber die Krankheiten III
irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...
متن کامل1,3,5-Tri-p-tolylpentane-1,5-diol
In the title compound, C26H30O2, the central benzene ring forms dihedral angles of 14.85 (15) and 28.17 (14)° with the terminal benzene rings. The dihedral angle between the terminal benzene rings is 32.14 (13)°. The crystal packing exhibits two strong inter-molecular O-H⋯O hydrogen bonds, forming directed four-membered co-operative rings. A region of disordered electron density, most probably ...
متن کامل1,3,5-Tri-p-tolylpentane-1,5-dione
In the crystal structure of the title compound, C(26)H(26)O(2), the dihedral angle between the tolyl rings at each end of the 1,5-dione chain is 70.3 (1)°; the tolyl group at the middle of the chain makes dihedral angles of 67.8 (2) and 85.1 (2)° with the terminal rings. One benzene C atom and one methyl-ene C atom inter-act with a carbonyl O atom of an adjacent mol-ecule through C-H⋯O hydrogen...
