Abstract

A novel Mn4 mixed salt, {[(n-Bu4N)(ClO4)2]2[Mn4O6(Tacn)4](ClO4)} · 2H2O (I) and its analogue [Mn4O6(Tacn)4](ClO4)4 · 2H2O (II) (Tacn = 1,4,7-triazacyclononane), have been constructed and structurally characterized by X-ray crystallography. The [Mn4O6]4+ core of these two complexes presents an adamantine-like skeleton. Each Mn atom of both complexes is coordinated by three nitrogen atoms of Tacn and connects other Mn atoms through a single-oxo bridge in an octahedral environment. Two complexes crystallize in monoclinic crystal system, space group C2/c with a = 24.296(11) Å, b = 10.986(5) Å, c = 32.746(15) Å, β = 101.975(6)°, Z = 8 for I and space group P21/n with a = 21.141(10), b = 11.306(5), c = 21.576(10) Å, β = 111.155(5)°, Z = 4 for II.
