    • Disclosed herein is a bi-metallic cross-linking reagent according to the following formula: ##STR1## where M.sub.1 is a metal ion species capable of forming a complex of coordination number four or coordination number six; wherein L.sub.1, L.sub.2, L.sub.3, and L.sub.4 are each independently a halide, ammonia, dimethyl sulfoxide, carboxylate, thiolate, imidazole, a nucleobase, or an empty coordination site, provided that no more than two of L.sub.1, L.sub.2, L.sub.3, and L.sub.4 are empty coordination sites; wherein M.sub.2 is a metal ion species capable of forming a complex of coordination number two with a first ligand that is a hydrocarbon moiety and a second ligand that is kinetically lablie; and wherein n is an integer from two to nine. Also disclosed are cross-linked species, methods of preparing the crosslinking reagents of the invention, and methods for their use in tissue-specific targeting of anti-tumor agents.
