4-Chloro-2′,4′,6′-triethylbenzophenone: a redetermination
THE STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: (4-chloro-phen-yl)(2,4,6-trimethyl-phen-yl)methanone], C(19)H(21)ClO, has been redetermined at 100 K. The redetermination is of significantly higher precision than the previous structure determination at 133 K and reveals disorder of the one of the o-ethyl groups [occupancy factors = 0.77 (1) and 0.23 (1)] that was not identified in the prev...
متن کاملLow-temperature redetermination of 4-chloro-2-[tris(hydroxymethyl)methyliminomethyl]phenol as zwitterionic 4-chloro-2-[tris(hydroxymethyl)methyliminiomethyl]phenolate
The title Schiff base, C(11)H(14)ClNO(4), originally refined as a neutral mol-ecule [Chumakov, Antosyak, Mazus, Tsapkov & Samus (2000), Crystallogr. Rep.45, 945-950], is inter-preted as a zwitterionic compound. There are two independent zwitterions in the asymmetric unit. Five of the six hydr-oxy groups of the -CH(2)OH fragments are disordered. In one zwitterion, two are disordered over three s...
متن کاملRedetermination of 4-hydroxybenzaldehyde
This is a redetermination of the structure of the title compound, C(7)H(6)O(2), which was first reported by Iwasaki [Acta Cryst. (1977 ▶), B33, 1646-1648]. The results are obtained with greater precision in the present study. Crystal packing is stabilized by inter-molecular O-H⋯O inter-actions between the hydroxyl and aldehyde groups which link the mol-ecules into chains in a zigzag pattern alo...

متن کاملRedetermination of 4-nitrostilbene
In the title compound, C(14)H(11)NO(2), the benzene rings are inclined to each other with a dihedral angle between their mean planes of 8.42 (6)°. The nitro group is almost coplanar with the attached benzene ring but is rotated about the C-N bond by 5.84 (12)°. This redetermination results in a crystal structure with significantly higher precision than the original determination [Hertel & Romer...
