An isomorphous family of mixed 3d-4f dodenuclear aggregates, {[Mn III8Ln4(Clshi)8(OAc) 6(μ3-OCH3)2(μ3-O) 2(CH3OH)12(H2O)2] ·4CH3OH·xH2O)} (where Ln = EuIII (1), GdIII (2), TbIII (3), and DyIII (4); ClshiH3 = 5-chlorosalicylhydroxamic acid; x = 5 for 1 and 3; x = 6 for 2; x = 2 for 4), were synthesized and characterized. They were obtained from the reaction of ClshiH3 with Mn(OAc)2·4H 2O and Ln(NO3)3·6H2O. These isomorphous mixed 3d-4f compounds represent a family of novel structures with lanthanide ions in the metallacrown (MC) ring. Each dodecanuclear aggregate contains two offset stacked 14-MC-5 units with M-N-O-M-N-O-Ln-O-N-M-O-N-M connectivity to capture one LnIII ion in the core of each MC. Two 14-MC-5 units are connected through O ions with four Mn ions and six O atoms arranged in a double Mn4O6 cubane. Magnetic measurement indicates that antiferromagnetic interactions are present between the metal ions. The DyIII analogue with high anisotropy and large spin shows slow magnetization relaxation at a direct-current field of 2 kOe.

Members of the series of title compounds were tested for potential antipsychotic activity in relevant receptor binding assays and behavioral screens.Structure-activity relationships within the series are discussed.Compound 24 (BMY 13859-1), a (1,2-benzisothiazol-3-yl)piperazine derivative, was selected for further study because of its potent and selective profile in primary CNS tests.It was active in the Sidman avoidance paradigm and blocked amphetamine-induced stereotyped behavior in dogs for up to 7 h.The compound's lack of typical neuroleptic-like effects in therat catalepsy test and its failure to produce dopamine receptor supersensitivity following chronic administration indicate that it should not cause the movement disorders commonly associated with antipsychotic therapy.Although 24 has potent affinity for dopaminergic binding sites, its even greater affinity for serotonin receptors suggests that a serotonergic component may be relevant to its atypical profile.Compound 24 is currently undergoing clinical evaluation in schizophrenic patients.
