Synthesis and molecular and supramolecular structures of a series of triarylphosphines P(Ph)3–n4-RO-3,5-(tBu)2-C6H2}n (n = 1, 3; R = SiMe3, H) are reported. Chemical oxidation products E=P(Ph)3–n4-RO-3,5-(tBu)2-C6H2}n (E = O, S, and Se; n = 1, 3; R = SiMe3, H) are also reported. Crystal structures of the reported compounds were determined by single-crystal X-ray diffraction, using a Hirshfeld atom refinement
一系列三芳基膦的合成及分子和超分子结构 P(Ph) 3– n 4-RO-3,5-( t Bu) 2 -C 6 H 2 } n ( n = 1, 3; R = SiMe 3 , H) 被报道。化学氧化产物 E=P(Ph) 3– n 4-RO-3,5-( t Bu) 2 -C 6 H 2 } n (E = O, S, and Se; n = 1, 3; R = SiMe 3, H) 也有报道。报道的化合物的晶体结构通过单晶 X 射线衍射测定,使用 NoSpherA2 到 OLEX2 的 Hirshfeld 原子精修,C-C 键距离精度平均提高了 35%。n = 1, R = H 和n = 3, R = SiMe 3 , H的膦碱度使用各硒化物的1 J P,Se值确定;1 J P,Se = 699 Hz 对于 E = Se, n= 3,X = H 确定了有史以来报道的最基本的三芳基膦。分子间相互作用允许将
