The title compound, (NH)(CHN)[VO]·6HO, crystallizes with the deca-vanadate anion placed on an inversion centre in space group . This anion is surrounded by a first shell of ammonium cations and water mol-ecules, forming efficient N-H⋯O and O-H⋯O hydrogen bonds. A second shell includes metforminium monocations with a twisted geometry, also forming numerous inter-molecular hydrogen bonds. The complex three-dimensional network of non-covalent inter-actions affords a crystal structure in which the cations and anions are densely packed.
标题化合物(NH)(CHN)[VO]·6HO在空间群中，十钒酸根阴离子位于一个反演中心上结晶。该阴离子被第一层铵阳离子和水分子包围，形成有效的N-H⋯O和O-H⋯O氢键。第二层包括具有扭曲几何形状的二甲双胍单阳离子，也形成许多分子间氢键。非共价相互作用的复杂三维网络提供了一种阳离子和阴离子紧密堆积的晶体结构。
