A novel complex [Ru(phen)3][Cu(opba)]‧6H2O has been prepared and characterized structurally. The crystal structure showed that the complex consisted of dication [Ru(phen)3]2+ and complex dianion [Cu(opba)]2–. The IR, Uv-vis, EPR spectra were studied, and EPR spectra showed hyperfine structure from copper isotopes 63Cu and 65Cu, and superhyperfine(shf) from 14N coupling, giving parameters g// = 2.207,g = 2.026,A//Cu = 196 G,ACu = 43 G,A//N = 13 G,AN = 17 G. The bond parameters were evaluated based on the EPR spectra, indicating substantial π-bonding character in the Cu–N and Cu–O bonds in the complex [Cu(opba)]2–. The spin density on nitrogen and oxygen atoms is 0.081 and 0.195, respectively.
