The title compound, (CHN)[(CHNO)(MoO)]·4HO, which crystallizes in the monoclinic 2/ space group, was obtained by mixing molybdenum oxide, ethyl-enedi-amine and ethyl-enedi-amine-tetra-acetic acid (Hedta) in a 2:4:1 ratio. The complex anion contains two MoO units bridged by an edta anion. The midpoint of the central C-C bond of the edta anion is located on a crystallographic inversion centre. The independent Mo atom is tridentately coordin-ated by a nitro-gen atom and two carboxyl-ate groups of the edta ligand, together with the three oxo ligands, producing a distorted octa-hedral coordination environment. In the three-dimensional supra-molecular crystal structure, the dinuclear anions, the organo-ammonium counter-ions and the solvent water mol-ecules are linked by N-H⋯O, N-H⋯O and O-H⋯O hydrogen bonds.
标题化合物(CHN)[(CHNO)(MoO)]·4HO以单斜晶系2/空间群结晶，通过按2:4:1的比例混合氧化钼、乙二胺和乙二胺四乙酸（Hedta）制得。该络合阴离子包含由一个edta阴离子桥连的两个MoO单元。edta阴离子中心C-C键的中点位于一个晶体学反演中心上。独立的Mo原子由edta配体的一个氮原子和两个羧酸根基团以三齿方式配位，再加上三个氧代配体，形成一个扭曲的八面体配位环境。在三维超分子晶体结构中，双核阴离子、有机铵抗衡离子和溶剂水分子通过N-H⋯O、N-H⋯O和O-H⋯O氢键相连。
