Abstract:
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.
