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.

A method for lowering serum uric acid is disclosed which comprises administering to a human for its uricosuric activity a pharmaceutical composition comprising 7-chloro-2-methyl-3,3a-dihydro-2H,9H-isoxazolo (3,2-b) (1,3)-benzoxazin-9-one. 7-chloro-2-methyl-3,3a-dihydro-2H,9H-isoxazolo (3,2-b) (1,3) benzoxazin-9-one is a useful compound having valuable pharmacological properties, for example, it is a valuable anti-inflammatory agent, as evidenced by its ability to inhibit the local edema formation characteristic of inflammatory states when administered systemically to warm-blooded animals.
