英文摘要	A nickel diphosphate with mixed cations, Na(NH4)[Ni-3(P2O7)(2)(H2O)(2)] with a layered structure has been synthesized under hydrothermal conditions for the first time and characterized by single crystal X-ray diffraction, IR spectroscope and magnetization measurements. The structure consists of cis- and trans-edge sharing NiO6 octahedral chains linked via P2O7 units to [Ni3P4O16](2-) layers. The ammonium and sodium cations are alternately located in the interlayer spaces. The mixed cations play an important role in the structural formation of this layered compound, leading to a new layer-stacking variant. The magnetic susceptibility obeys a Curie-Weiss law with mu(eff) of 3.32 mu(B), showing the Ni2+ character and weak antifeffomagnetic interactions. (C) 2004 Elsevier SAS. All rights reserved.
