Synthesis and Single Crystal XRD of Hydroniumpentaaquabis(1,10-phenanthroline) europium(III)tetrachloride Hydrate [(H3O+)(H2O)5(phen)2Eu(III)]Cl4.H2O

A novel europium(III)-1,10-phen complex (I) has been synthesized and characterized by single crystal XRD. Complex I crystallized in the monoclinic space group C2/c with unit cell dimensions a = 30.8233(13) Å, b = 9.5063(4) Å, c = 21.9973(10) Å, α = 90°, β = 113.616(2)°, γ = 90°, and Z = 4. The structure involves several hydrogen bond donor and acceptor sites leading to the formation of a supramolecular architecture.
