Stabilization of O–Mn–O clusters (Mn5) in three dimensionally extended MOF structures: synthesis, structure and properties

Abstract

Four new three-dimensional Mn2+ ion-containing compounds have been prepared by employing a hydrothermal reaction between Mn(CH3COO)2·4H2O, sulfodibenzoic acid (H2SDBA), imidazole, alkali hydroxide and water at 220 °C for 1 day. The compounds have Mn5 (14) clusters connected by SDBA, forming the three-dimensional structure. A time and temperature dependent study on the synthesis mixture revealed the formation of a one-dimensional compound, Mn(SDBA)(H2O)2, at lower temperatures (T ≤ 180 °C). The stabilization of the fcu related topology in the compounds is noteworthy. Magnetic studies indicate strong anti-ferromagnetic interactions between the Mn2+ ions within the clusters in the temperature range 75–300 K. The rare participation of a sulfonyl group in the bonding is important and can pave way for the design of new structures.
