摘要

A novel Mn-4 mixed salt, {[(n-Bu4N)(ClO4)(2)](2)[Mn4O6(Tacn)(4)](ClO4)} center dot 2H(2)O (I) and its analogue [Mn4O6(Tacn)(4)](ClO4)(4) center dot 2H(2)O (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) , b = 10.986(5) , c = 32.746(15) , beta = 101.975(6)A degrees, Z = 8 for I and space group P2(1)/n with a = 21.141(10), b = 11.306(5), c = 21.576(10) , beta = 111.155(5)A degrees, Z = 4 for II.
