无水氰化氢在室温下与四氯化钒反应，生成一种配位化合物VCl 4（NCH）2。晶体为正交晶系，a=11.964 ± 0.007，B=10.647 ± 0.007，c=6.503 ± 0.003，Z=4，空间群P212121。晶体结构通过X射线解析。将正规方程的全矩阵求逆并使用各向异性温度因子，基于681个反射的R因子等于0.041，不包括零值。钒原子在顺式位置被四个氯原子和两个氮原子八面体包围。配位八面体与可见光和紫外分光光度法一致，有轻微的畸变。一个八面体的一个氢原子与另一个八面体的一个氯原子键合。
Abstract Anhydrous hydrogen cyanide reacts at room temperature on vanadium tetrachloride to give a coordination compound VCl4(NCH)2. Crystals are orthorhombic with a=11.964 ± 0.007, b=10.647 ± 0.007 and c=6.503 ± 0.003 A, Z=4, space group P212121. Crystal structure is resolved by X-ray. Inverting the full matrix of normal equations and using anisotropic temperature factors, the R factor based on 681 reflexions is equal to 0.041 excluding zero values. The vanadium atom is surrounded octahedrally by four chlorine atoms and two nitrogen atoms in the cis position. The coordination octahedron is slightly distorted in agreement with visible and U.V. spectrophotometry. One hydrogen atom of one octahedron is bonded to a chlorine atom of another octahedron.
