LnL4(ClO4)3 (Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu; L = 1,8-naphthyridine N-oxide) were prepared and characterized by IR spectra, DTA, TG and elec. conductivity measurements. EuL4(ClO4)3 is monoclinic, space group C2/c, with a 27.790(2), b 10.676(1), c 14.190(2) ? b 118.03(2)? do = 1.86, dc = 1.85 g cm-3, R = 0.081, Rw = 0.090. L is bidentate, coordinating through the N and O atoms. The coordination no. of Eu is 8.
