Abstract
A triangular Dy(III) single-molecule magnet (SMM) exhibiting ferroelectric bistability is assembled in an acentric space group Pna2(1). Hysteresis loops associated with its SMM behavior together with a two-step slow relaxation of the magnetization are observed below 30 K. A transition with dielectric anomalies between a paraelectric and a ferroelectric phase occurs at 470 K.
