چکیده
In the title compound, C21H13ClO, the central anthracene system is distorted towards a boat conformation and the outer rings are not coplanar with the central ring [dihedral angles = 7.79 (1) and 11.90 (1)°]. The crystal structure features inversion dimers with graph-set motif R 2 (2)(18) formed by C-H⋯O inter-actions.

The crystal structure of the title compound, C(28)H(18)O(2), was originally determined by Ehrenberg [(1967 ▶). Acta Cryst. 22, 482-487] using intensity data obtained from Weissenberg photographs. The current determination provides a crystal and mol-ecular structure with a significantly higher precision and presents standard uncertainties on geometric parameters which are not available from the ...

In the title compound, C22H18ClN3O, the carbazole ring system is essentially planar (r.m.s deviation = 0.003 Å), and makes a dihedral angle of 9.01 (8)° with the plane of the chloro-phenyl ring. In the crystal, neighbouring mol-ecules are linked into centrosymmetric R 2 (2)(8) dimers by pairs of N-H⋯O inter-actions and into a three-dimensional network by C-H⋯π inter-actions. The dimers are arra...
متن کامل( 2 S ) - [ 3 - ( Anthracen - 9 - yl ) - 4 , 5 - dihydroisoxazol - 5 - yl ] methyl 2 - [ ( tert - butoxycarbonyl ) amino ] propanoate
The synthesis of the (2S)-[3-(anthracen-9-yl)-4,5-dihydroisoxazol-5-yl]methyl 2-[(tert-butoxycarbonyl)amino]propanoate is obtained through the 1,3-dipolar cycloaddition of the stable anthracenenitrile oxide and the N-Boc protected (S)-alanine allyl ester as dipolarophile. The structure and the fluorescence properties are described upon the relative analytical and spectroscopic data.

The title compound, [Ni(C(35)H(29)N(3)O(3))], includes a Schiff base ligand derived from (S)-1-[(anthracen-9-yl)meth-yl]-N-(2-benz-oyl-phen-yl)pyrrolidine-2-carboxamide and glycine. The Ni(II) atom is coordinated by three N atoms [Ni-N = 1.937 (3), 1.850 (3) and 1.850 (3) Å] and one O atom [Ni-O = 1.859 (2) Å], resulting in a pseudo-square-planar coordination environment.
