Diethyl 2-[(4-nitrophenyl)(4-phenyl-1,2,3-selenadiazol-5-yl)methyl]malonate

Abstract

In the title compound, C22H21N3O6Se, the heterocyclic ring makes dihedral angles of 50.03 (11) and 67.75 (11)°, respectively, with the benzene and phenyl rings. The terminal C atoms of the ester groups are disordered over two positions: the site occupancies for the C atoms are 0.62 (3)/0.38 (3) and 0.48 (3)/0.52 (3). In the crystal structure, weak intra- and intermolecular C—H...O interactions are observed.
