摘要

标题化合物C36H28OP2S2(1)和C36H28OP2Se2(2)虽然不是同构的,但结构非常相似。化合物(2)的整个分子是由双重对称生成的,醚O原子位于双轴上。两种化合物在(1)和(2)中,端苯环之间的分子内π-π相互作用,质心距离分别为3.6214(16)和3.8027 (14)Å。在(1)的晶体中,短的C-H⋯S氢键连接分子,沿着[001]形成链,而在(2)中没有类似的C-H⋯Se相互作用。

Crystal structures of bis-[2-(di-phenyl-phosphino-thio-yl)phen-yl] ether and bis-{2-[diphen-yl(selanyl-idene)phosphan-yl]phen-yl} ether.

Crystal structures of bis-[2-(di-phenyl-phosphino-thio-yl)phen-yl] ether and bis-{2-[diphen-yl(selanyl-idene)phosphan-yl]phen-yl} ether.

Crystal structures of bis-[2-(di-phenyl-phosphino-thio-yl)phen-yl] ether and bis-{2-[diphen-yl(selanyl-idene)phosphan-yl]phen-yl} ether.

Crystal structures of bis-[2-(di-phenyl-phosphino-thio-yl)phen-yl] ether and bis-{2-[diphen-yl(selanyl-idene)phosphan-yl]phen-yl} ether.

The title compounds, C36H28OP2S2, (1), and C36H28OP2Se2, (2), exhibit remarkably similar structures although they are not isomorphous. The whole mol-ecule of compound (2) is generated by twofold symmetry, with the ether O atom located on the twofold axis. Both compounds have intra-molecular π-π inter-actions between terminal phenyl rings with centroid-centroid distances of 3.6214 (16) and 3.8027 (14) Å in (1) and (2), respectively. In the crystal of (1), short C-H⋯S hydrogen bonds link the mol-ecules, forming chains along [001], while in (2) there are no analogous C-H⋯Se inter-actions present.

期刊介绍: Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
