New manganese compounds [Mn(HphpzMe) 2 (H 2 phpzMe)(HCO 2 )] ( 1 ), [Mn 2 (phpzMe) 2 (HphpzMe) 2 (OCH 3 )]·2CH 3 OH ( 2 ), Na{[Mn(HphpzPh)(phpzPh)(MeOH) 2 ] 2 }(HCO 2 ) ( 3 ), [Mn(HphpzPh) 2 (EtOH) 2 ]ClO 4 ·2EtOH ( 4 ) and [Mn(HphpzPh) 2 N 3 ] ( 5 ) were synthesized and characterized with various techniques. 1 , 4 and 5 are mononuclear manganese( iii ) compounds, 2 is a mixed-valence dinuclear manganese( iii / iv ) compound, and 3 is a trinuclear compound containing two manganese( iii ) ions and a sodium( i ) ion. A remarkable feature is the spontaneous formation of the formate ion as a result of the methanol or methoxide oxidation in compounds 1 and 3 . Using ethanol precludes the formation of the formate and compound 4 is obtained. The molecular structure of all compounds is stabilized by supramolecular interactions, including strong hydrogen bonding and - interactions. New manganese compounds were synthesized with two different phenol-pyrazole ligands. All compounds are stabilized by H-bonding and - interactions.
