Salts bearing the tetracyanopyrrolide anion (TCP) were synthesized from tetracyano-1,4-dithiin and sodium azide according to a modified synthetic protocol. The solid-state structures of HTCP, MeTCP, Me4NTCP, NaTCP, and the ionic liquid EMIMTCP (EMIM = 1-ethyl-3-methylimidazolium) are discussed for the first time. According to experimental and computational data, the TCP anion can be regarded as a pseudohalide
带有四氰基吡咯烷阴离子 (TCP) 的盐是根据修改后的合成方案由四氰基-1,4-二噻英和叠氮化钠合成的。首次讨论了 HTCP、MeTCP、Me4NTCP、NaTCP 和离子液体 EMIMTCP(EMIM = 1-ethyl-3-methylimidazolium)的固态结构。根据实验和计算数据,TCP 阴离子可以被视为一种伪卤化物,其 π 键在包括四个氰基在内的整个阴离子上高度离域。平面阴离子是 C2v 对称的,代表多功能二元 CN 配体,能够通过 CN 基团的孤对或环氮原子形成经典的配位键。此外,
