Diethyl 2-[(4-nitro-phen-yl)(4-phenyl-1,2,3-selenadiazol-5-yl)meth-yl]malonate.


ABSTRACT: In the title compound, C(22)H(21)N(3)O(6)Se, 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 inter-molecular C-H?O inter-actions are observed.

In the title compound, C(22)H(21)N(3)O(6)Se, 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).
