The reaction of calcium naphthyridine‐2,7‐dicarboxylate (Cadcnp) with Ru 2 (OAc) 4 Cl in water resulted in the formation of Ca[Ru 2 (dcnp)(OAc) 3 ] 2 ( 3 ). X‐ray crystal structural analysis of 3 confirmed its molecular structure and showed that the calcium ion binds to the lateral carboxylate groups of four neighboring anionic units of [Ru 2 (dcnp)(μ‐OAc) 3 ] and two acetone molecules to form a two‐dimensional framework. The Ru II –Ru II valence state of the diruthenium core was supported by superconducting quantum interference device (SQUID) magnetometry [ μ eff (300 K) = 2.77 μ B ]. Complex 3 appears to be an efficient catalyst for the oxidative cleavage of olefins in aqueous media under mild conditions. Typically, the reaction of pulegone with NaIO 4 in water catalyzed by 3 (1 mol‐%) at 45 °C afforded 3‐methyladipic acid quantitatively.
