title: Bis[S-6-(2,2:6',2''-terpyridin-4'-yloxy)hexyl thioacetate]manganese(II) bis(hexafluorophosphate).
abstract: The structure of a manganese(II) complex of terpyridine functionalized with acetylsulfanyl-terminated hexyloxy chains, [Mn(C(23)H(25)N(3)O(2)S)(2)](PF(6))(2), is described. This type of complex is of interest in the study of single-molecule transport properties in open-shell systems. The manganese coordination environment is distorted octahedral but, importantly, with no larger deviations from the idealized geometry than those observed for other metal-terpyridine complexes. The Mn-N bond lengths range from 2.192 (2) to 2.272 (3) A. The title compound crystallizes with the cation and anions all on general positions, with the hexafluorophosphate anions exhibiting orientational disorder. When compared with other bis-terpyridine complexes, this structure demonstrates that manganese(II) is no more prone to undergo low-symmetry distortions than systems with ligand field stabilization energy contributions.
