and a tetrahedral one. The octanuclear cluster Zn(8)(shi)(4)(pko)(4)(CH(3)OH)(2) contains a 12-membered tetranuclear metallacrown core constructed by four Zn metal atoms and four shi(3-) ligands. So, a part of the cluster can be described as having the formally anionic [12-MC(Zn(II)N(shi))-4](4-) core. Two of the zinc atoms are in octahedral coordination environment while for the other two the geometry
