Syntheses and magnetic properties of new compounds Ca3M3(PO4)4 (MÂ =Â Ni, Co) with a wave-like layer structure built by zigzag M-chains

The linkage of M-polyhedra in Ca3M3(PO4)4 (M = Ni and Co) shows a wave-like network in which the V-like clusters are inserted alternatively between the zigzag chains.370
