A Mn 17 octahedron with a giant ground-state spin: Occurrence in discrete Form and as Multidimensional coordination polymers

Abstract

A [Mn lll 11Mn ll 6(μ 4-O) 8(μ 3-L) 4] 25+ (L = N 3 - or OCN -) octahedral unit is reported, occurring within 1D (1)∞ and 2D (2)∞ coordination polymers, as well as the corresponding 0D discrete cluster 3. It possesses a giant ground-state spin value, determined in the case of 3 to be S= 37, the second largest to be reported to date. In addition, compound 3 displays single-molecule magnet (SMM) behavior, and is thus the largest-spin SMM. © 2009 American Chemical Society.
