Bis(4-acetylphenyl) selenide

Abstract

In the title compound, C16H14O2Se, the dihedral angle between the benzene rings is 87.08 (11)°. In the crystal, mol­ecules are linked into layers parallel to the bc plane by inter­molecular C—H⋯O hydrogen bonds.

Bis(4-nitrophenyl) selenide

“…The C-Se-C angle is 99.48 (13)°, that is similar to 99.58 (13)° observed in bis(4-acetylphenyl) selenide (Bouraoui et al, 2011), but different from 106.2 (1)° found in bis(p-tolyl) selenide (Blackmore & Abrahams, 1955). Two benzene rings in (I) are inclined to each other at 63.8 (1)° and each nitro group is twisted at 15.9 (1)° from the attached benzene ring.…”

“…For details of the synthesis, see: Taniguchi (2005). The crystal structures of the related compounds bis(p-tolyl) selenide and bis(4-acetylphenyl) selenide were reported by Blackmore & Abrahams (1955) and Bouraoui et al (2011), respectively.…”

“…The C1-Se1-C16 angle is 99.0 (2) , which is close to the value observed in three very similar compounds, viz. 99.47 (10) in bis(4-nitrophenyl) selenide, where the Se atom lies on a twofold rotation axis (Zuo, 2013), 99.59 (14) in bis(4acetylphenyl) selenide (Bouraoui et al, 2011) and 100.03 (15) in bis(2-chloroethan-1-one-phenyl) selenide (Bouraoui et al, 2015).…”

“…1, the C1-Se1-C7 angle is 100.05 14°, similar to the value observed in two very similar compounds, viz. ca 99.47 ° in bis(4-nitrophenyl)selenide (Zuo, 2013), and 99.59 (14)° in bis(4-acetylphenyl) selenide (Bouraoui et al, 2011) where the Se atom lies on a two-fold rotation axis. In the title compound the two benzene rings are inclined to one another by 69.92 (17) °.…”
