Abstract

This paper reports on the synthesis, structure and magnetic properties of a new type of rod like Mn₁₂ metal cluster, [Mn₁₂O₇(OH)₂(OMe)₂(dmhmp)₄(O₂CPh)₁₁(H₂O)] (6) where the ligand (dmhmpH) is 2-(pyridine-2-yl)propan-2-ol. Compound (6) was obtained by reacting MnCl₂·4H₂O with dmhmpH in the presence of benzoic salt and Et₃N. The resulting crystalline material is assigned to the triclinic space group P [1 with combining macron] . Although compound (6) displays ferromagnetic and antiferromagnetic competition behavior, this does not prevent the molecule from functioning as a single-molecule magnet (SMM). The SMM behavior is evidenced by observing frequency dependent out-of-phase ac signals as well as magnetization hysteresis loops at low temperatures in a micro-SQUID study. A brief comparison between all rod-like Mn₁₂ materials is also given in the manuscript.
