Abstract

A heterometallic 3d-4f compound formulated as {[CoIII2Dy3Na(CH3CH2COO)6(OH)6(NO3)4(H2O)2]·H2O}n (1) has been synthesized and structurally characterized. The Co2Dy3 metal core adopts trigonal bipyramidal (TBP) geometry. Compound 1 displays single-molecule magnet behavior with an energy barrier of 60.3 K under a zero dc field.
