Two novel hypervalent selenium(IV) compounds stabilized by intramol. interactions, namely 6-phenyl-6,7-dihydro-5H-2,3-dioxa-2aλ4-selenacyclopenta[hi]indene, C14H12O2Se, 14, and 5-phenyl-5,6-dihydro-4H-benzo[c][1,2]oxaselenole-7-carbaldehyde, C14H12OSe2, 15, have been synthesized by the reaction of 2-chloro-1-formyl-3-(hydroxymethylene)cyclohexene with in-situ-generated disodium diselenide (Na2Se2). The title compounds were characterized by FT-IR spectroscopy, ESI-MS, and single-crystal X-ray diffraction studies. For 14, there is whole-mol.disorder, with occupancies of 0.605 (10) and 0.395 (10), a double bond between C and Se, and the five-membered selenopentalene rings are coplanar. The packing is stabilized by p-p stacking interactions involving one of the five-membered Se/C/C/C/O rings [centroid-centroid (Cg···Cg) distance = 3.6472 (18) Å and slippage = 1.361 Å], as well as C-H···p interactions involving a C-H group and the Ph ring. In addition, there are bifurcated C-H···Se,O interactions which link the mols. into ribbons in the c direction. For 15, the C-Se bond lengths are longer than those of 14. The two five-membered rings are coplanar. There are no p-p or C-H···p interactions; however, mols. are linked by C-H···O interactions into centrosym. dimers, with graph-set notation R22(16).
