A niccolite series of [bnH 2 2+ ][M(HCOO) 3 ] 2 (bnH 2 2+ =1,4‐butyldiammonium) shows four kinds of metal‐dependent phase transitions, from high temperature para‐electric phases to low‐temperature ferro‐, antiferro‐, glass‐like, and para‐electric phases. The conformational flexibility of bnH 2 2+ and the different size, mass, and bonding character of the metal ion lead to various disorder‐order transitions of bnH 2 2+ in the lattice and relevant framework modulations, thus different phase transitions and dielectric responses. The magnetic members display a coexistence or combination of electric and magnetic orderings in the low‐temperature region.
