M3(P2O7)22--type open frameworks featuring [M2O8] and [M3O12] multinuclear transition-metal oxide units. Serendipitous synthesis of six polymorphic salt-inclusion magnetic solids: Na2M3(P2O7)2·ACl (M = Mn, Fe; A = Rb, Cs) and K2M3(P2O7)2·CsCl (M = Fe, Mn).
TL;DR: The title compounds have demonstrated an unprecedented versatility, where the M(3)(P(2)O(7))(2)(2-) covalent open frameworks contain trimeric units in 1-4 and [M(2]O(8)] dimers in 5 and 6, which suggests bulk antiferromagnetic properties as expected.
