Structural and magnetic characterization of alternating AB chains of composition [(Cat)2{MnIII(malonate)2(CH3OH)2][MnIII(malonate)2]}]n and (Cat)2[[MnIII(malonate)2(CH3OH)][MnIII(malonate)2]]n

The S=2 chain [(NH 4 + ) 2 [Mn III (malonate) 2 (CH 3 OH) 2 ] [Mn III (malonate) 2 ]] n (2) has been synthesized and structurally characterized by using X-ray diffraction methods. The basic motif of 2 is isostructural to that of the compounds [K 2 [Mn III (malonate) 2 (CH 3 OH) 2 ] [Mn III (malonate) 2 ]] n (1) and [(cat) 2 [Mn III (salicylate) 2 (CH 3 OH) 2 ] [Mn III -(salicylate) 2 ]] n
