在标题盐(C_7H_12N_6)[VOF_5]的结构中,V离子周围配位八面体的二级Jahn-Teller畸变反映为短V-O键[1.5767(12)<$]和反位长V-F键[2.0981(9)<$]的共存,其中四个赤道V-F距离的大小居中[1.7977(9)-1.8913(9)<$]。       阴离子的氢键仅限于F原子受体,轴向和顺式定位的赤道F原子建立了特别强的N-H F相互作用[N F = 2.5072(15)]。  Hirshfeld表面分析表明,最重要的相互作用绝大多数是H <$F/F <$H,分别占单个阴离子和阳离子接触的74.4%和36.8%。弱的CH <$F和CH <$N键对于生成三维结构是必不可少的。
In the structure of the title salt, (C7H12N6)[VOF5], second-order Jahn–Teller distortion of the coordination octahedra around V ions is reflected by coexistence of short V—O bonds [1.5767 (12) Å] and trans-positioned long V—F bonds [2.0981 (9) Å], with four equatorial V—F distances being intermediate in magnitude [1.7977 (9)–1.8913 (9) Å]. Hydrogen bonding of the anions is restricted to F-atom acceptors only, with particularly strong N–H⋯F interactions [N⋯F = 2.5072 (15) Å] established by axial and cis-positioned equatorial F atoms. Hirshfeld surface analysis indicates that the most important interactions are overwhelmingly H⋯F/F⋯H, accounting for 74.4 and 36.8% of the contacts for the individual anions and cations, respectively. Weak CH⋯F and CH⋯N bonds are essential for generation of three-dimensional structure.
