Indications of desirable polar order in ethylammonium C2H5NH3(EtA) metal formate [EtA][Na0.5Cr0.5(HCOO)3] and the lack of it in [EtA][K0.5Cr0.5(HCOO)3] raised important questions on the origin of structural phase transition and dipolar dynamics in th

In the last decade, one of the most widely examined compounds of motal-organic frameworks was undoubtedly ((CH3)2NH2)(Zn(HCOO)3), but the problem of the importance of framework dynamics in the order–disorder phase change of the mechanism has not be
