用X射线衍射仪测定了水溶液中三斜晶系[enH_2][VOF_5]的晶体结构（R = 0.076，共527次）。该结构含有单体[VOF 5]2-离子。键距为1.54（1）<$（末端氧原子）、1.80（1）（顺式氟原子的平均值）和2.10（1）<$（氟原子转位至末端氧原子）。该氟原子参与源自具有顺式构象的[NH3 CH 2CH 2NH 3]2+阳离子的强氢键。早期关于K2 VOF 5存在的结果无法得到证实
The crystal structure of triclinic [enH2][VOF5], prepared in aqueous solution, has been determined from X-ray diffractometer data (R = 0.076 for 527 reflections). The structure contains monomeric [VOF5]2--ions. The bond distances are 1.54(1) Å (terminal oxygen), 1.80(1) (average for the cis-fluorine atoms) and 2.10(1) Å for the fluorine atom in transposition to the terminal oxygen atom. This fluorine atom is involved in strong hydrogen bonds originating from the [NH3CH2CH2NH3]2+ cation with cisoid conformation. Earlier results about the existence of K2VOF5 could not be confirmed
