Elongation of magnetic relaxation times in a single-molecule magnet through intermetallic interactions: a clamshell-type dinuclear terbium(iii)-phthalocynaninato quadruple-decker complex.

A clamshell-type terbium(iii)-phthalocyaninato quadruple-decker complex was synthesized. Magnetic measurements revealed that Tb-Tb interactions caused an increase in the magnetic relaxation time and enhanced the SMM properties.
