Abstract: The title complex has been synthesized.In this complex there is only one tetraethy-lene glycol that acts as a pentadentate ligand and forms a ring-like structure.The excess coordination sites are satisfied by three thiocyanate ions and one water molecule.The coordination number of cerium is 9.The crystal structure of this complex was determined as follows:P1 space group with a=0.8816(3)nm,b=1.0465(2)nm,c=1.2490(2)nm,α=86.46(1)°,β=70.90(2)°,γ=66.37(2)°,V=0.9943 nm3,Z=2.The final deviation factor R=0.049,for 3497 unique reflections[I≥3°(I0)]
