通过将Np- vi原位还原为Np-IV，在水热条件下制备了层状甲基膦酸镎（IV） Np(CH3PO3)(CH3PO3H)(NO3)（H2O）中心点H2O。这种化合物的单晶结构显示极性层通过层间水分子的氢键网络相互连接。磁化率测量表明，Np-IV离子是相互磁隔离的。
A lamellar neptunium(IV) methylphosphonate, Np(CH3PO3)(CH3PO3H)(NO3)(H2O)center dot H2O, has been prepared under hydrothermal conditions via the in situ reduction of Np-VI to Np-IV. The single crystal structure of this compound shows polar layers that are joined to one another via a hydrogen-bonding network involving interlayer water molecules. Magnetic susceptibility measurements demonstrate that the Np-IV ions are magnetically isolated from one another.
