An attempt was made to prepare two series of tetrakis eight-coordinate tungsten(IV) and cerium(IV) complexes containing the 5,7-dichloro-8-quinolinol(N:<TEX>${\pi}$</TEX>-acceptor atom, O:<TEX>${\pi}$</TEX>-donor atom) ligand. Tetrakis eight-coordinate tungsten(IV) complex of 2-mercaptopyrimidine(N:<TEX>${\pi}$</TEX>-acceptor atom, S:<TEX>${\pi}$</TEX>-donor atom) ligand have also been prepared. And the new series of mixed-ligand eight-coordinate tungsten(IV) complexes containing bidentate ligands 5,7-dichloro-8-quinolinol and 2-mercaptopyrimidine have been prepared, isolated by TLC and characterized. <TEX>$W(dcq)_4$</TEX>, <TEX>$W(dcq)_3(mpd)_1$</TEX>, <TEX>$W(dcq)_2(mpd)_2$</TEX>, <TEX>$W(dcq)_1W(dcq)_3$</TEX> and <TEX>$W(mpd)_4$</TEX> complexes of MLCT absorption band appeared to 710nm, 680nm, 625nm, 581nm, and 571nm(<TEX>${\varepsilon}\;max
