The magnetic properties of two similar Er(3+) complexes have been investigated. [Er(tpm)3(bipy)] (Htpm = 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione and bipy = 2,2'-bipyridine) displays thermally activated slow relaxation of magnetisation under a zero direct-current (DC) field. Under an applied HDC field of 1000 G, [Er(tpm)3(bipy)] exhibits two thermally activated processes with energy barrier...

A one pot synthesis of an array of angularly linked tri-heterocycles with coumarin, benzofuran and furan rings is described. This high yielding synthesis is achieved by the reaction of various 4-bromomethylcoumarins with furyl o-hydroxyphenyl ketones involving benzylic nucleophilic displacement and intramolecular aldolization. All the compounds have been tested in vitro for their anti-microbial...
