A convenient method for the preparation of polypyridine complexes of Ru(II) within the supercages of zeolite Y is reported. The bis-heteroleptic trisligated species Ru{sup 2+}(bpy){sub 2}(bpz){sup 2+}-Y and Ru{sup 2+}(bpy){sub 2}(dmb){sup 2+}-Y have been obtained and characterized by electronic absorption and resonance Raman spectroscopies. Two methods of zeolite matrix destruction have been used to extract the zeolite-entrapped complexes. Depending on experimental conditions, a blue byproduct can be formed in the zeolite supercages. Preliminary evidence suggests that this compound is properly formulated as Ru{sup 3+}(bpy){sub 2}(X)0-(where X is unspecified) bound to the supercage interior wall via an oxygen atom donated by the zeolite.
