Interlayer ammine complexes of metal uranyl phosphates

The solids derived from HUP by substituting metallic ions for protons, take up Lewis base molecules (like NH 3 and C 4 H 9 NH 2 ) in the interlamellar space. The diffractograms of these inclusion compounds indicate that the host crystallinity was preserved.The infrared spectroscopy of the Ni, Co, Cu, Zn, and Cd intercalates revealed that part of the sorbate was protonated in the interlaminar space while the other part displaced the water in their coordination spheres. However, in the Mn derivative, no coordinated or free Lewis base could be detected: it was all in the protonated form.
