Cation-size-controlled assembly of the Ni(Ac)2-1,4-H2NDC system: geminal dicationic ionothermal syntheses, crystal structures and magnetic properties.

ABSTRACT

Geminal dicationic ionic liquids with different alkyl spacer lengths regularly tune four MOF structures of two structure types in the Ni(Ac)2-1,4-H2NDC system, which in turn bring about the magnetic properties divided into antiferromagnetic and ferromagnetic couplings consistent with the structures.
