A tri(8 quinolinol)nickel coordination compound, [Ni 2(HQ) 3Q 3] ClO 4, was synthesized and its crystal structure was determined by X ray diffraction. The crystal structure indicated a space group of P2 1/c with a =1.613 8(1) nm, b =1.590 0(1) nm, c =1.939 9(1) nm, β =94.663(2)°, V = 4.961 2(6) nm 3 and Z =4. Three strong hydrogen bonds were found in each unique unit between two tri(8 quinolinol) nickel fragments. The crystal structure was determined by X-ray diffraction.
