Mn₃(HCOO)₆: a 3D porous magnet of diamond framework with nodes of Mn-centered MnMn₄tetrahedron and guest-modulated ordering temperature

Abstract

Mn3(HCOO)6, a 3D highly stable and flexible porous diamondoid framework based on Mn-centered MnMn4 tetrahedral nodes, exhibits a wide spectrum of guest inclusion behaviour and long-range magnetic ordering with guest-modulated critical temperature.

A Porous Coordination‐Polymer Crystal Containing One‐Dimensional Water Chains Exhibits Guest‐Induced Lattice Distortion and a Dielectric Anomaly

“…[3][4][5][6] In addition to the functions that originate from the host lattices, porous crystals can exhibit functions that are derived from guest molecules. Thus, for example, we have reported the porous crystalline compound [Mn 3 (HCOO) 6 ](CH 3 OH)(H 2 O), which exhibits a dielectric anomaly associated with the "melting" (or "freezing") of the positional freedom of guest methanol and water molecules.…”

Magnetic functionalities in MOFs: from the framework to the pore

“…5). [20][21][22][23][24][25][26] The magnetic behaviour of these magnetic MOFs depends on the type of metal ion: the iron and manganese formates are ferromagnets, with critical temperatures T c of 16.1 and 8.0, whereas the cobalt compound is a spin-canted antiferromagnet below 1.8 K and the nickel derivative displays 3D long-range ferromagnetic ordering at 2.7 K (see Fig. 5b).…”
