In an attempt to employ salicylic acid (HOsalH), 2,6-dihydroxy benzoic acid {(HO)(2)PhCO2H}, and naphthalene-1,8-dicarboxylic acid {1,8-naph(CO2H)(2)} in Mn(III) salicylaldoximate chemistry as a means to alter the structural identity of the hexanucluear clusters usually obtained from this reaction system, we have isolated a family of hexanuclear Mn(III) complexes based on salicyladloxime (saoH(2)) and 2-hydroxy-1-naphthaldehyde oxime (naphthsaoH(2)). Five hexanuclear clusters, [Mn6O2(sao)(6)(HOsal)(2)(EtOH)(4)]center dot EtOH (1 center dot EtOH), [Mn6O2(sao)(6){1,8-naph(CO2Me)(CO2)}(2)(MeOH)(6)]3MeOH (23MeOH), [Mn6O2(naphthsao)(6){1,8-naph(CO2Et)(CO2)}(2)(EtOH)(6)] (32MeOH), [Mn6O2(naphthsao)(6)(MeCO2)(2)(EtOH)(4)]2H(2)O (42H(2)O), and [Mn6O2(naphthsao)(6){(HO)(2)PhCO2}(2)(EtOH)(4)]4EtOH (54EtOH), have been synthesized and characterized by single-crystal X-ray crystallography. The magnetic properties of 3, 4, and 5 are discussed.
