N,N,N',N'-tetra [(2-benzimidazolyl) methyl]-l,2-ethanediamine (EDTB) lanthanidechloride complexes were prepared (Ln³⁺=Eu³⁺, Tb³⁺or Gd³⁺). The results of single crystal X-ray structural analysis show that [(EDTB) GdCl₂]Cl(C₂H₅OH)(H₂O)₂ crystal is in space group P2₁/c with a=8.848(2) Å, b=26.313(5) Å, c=18.929(4) Å, β=97.82 (3)°, V=4366(2) Å3, Z=4. The luminescent properties of the terbium and europium complexes have been studied.
