Abstract

The title compound, C18H17NO2, was prepared from 1-hydr­oxy-8-methyl­carbazole and 3,3-dimethyl­acrylic acid with trifluoro­acetic acid as the cyclization catalyst. Due to the –CMe2– group, the mol­ecule is not quite planar. The packing is dominated by

Abstract

In the title compound, C17H14O3, the dihedral angle between the phenyl ring and the benzene ring of the chromanone moiety is 67.78 (3)°. The six-membered heterocyclic ring of the chromanone moiety adopts a half-chair conformation. The structure is stabilized by we

Abstract

The title compound, C11H12N4O4, was synthesized by the reaction of (2,4-dinitro­phen­yl)hydrazine with cyclo­penta­none. The cyclo­pentyl fragment is disordered over two sites with occupancies of 0.63 (1) and 0.37 (1). An intra­molecular N—H⋯O hydrogen

Abstract

The title compound, [Cu2(C11H8NO3)2Cl2], is a bicopper(II) complex. Each CuII ion is five-coordinated by two O atoms and one N atom from the (8-quinol­yloxy)acetate ligand, and by two μ2-chloride ligands, thus
