Casting clusters from the mold : Tris(ethylzinc) phosphazenates exhibit a bowl‐shaped coordination surface of three Lewis acidic EtZn moieties and three Lewis basic N sites. This surface provides a perfect mold for planar {(ZnO) 3 } rings and hexagonal {(ZnO) 6 } prisms. The zinc oxide clusters were generated in situ by reaction of phosphazene hydrates with diethylzinc.
