Alk. earth-perchlorate complexes of the types ML2(ClO4)2.xH2O and MR2(ClO4)2.xH2O (M = Mg, Ca, Sr, Ba; 0 â?x â?3.5), where L is 1,8-naphthyridine and R is 2,7-dimethyl-1,8-naphthyridine (I) have been synthesized. The white crystalline compounds have been characterized by elemental analyses, molar conductances, and IR (4000-200 cm-1) and PMR spectroscopy. The steric influence of the Me groups of I does not affect the resulting stoichiometry. In a polar solvent, the compounds exhibit the expected 3-ion conductances. As deduced from the solid IR spectra, some of the perchlorates are distorted toward C3v symmetry. Distortion of the perchlorate in the crystal lattice and (or) a weak interaction of the metal ion and the perchlorate are offered as possibilities for this reduction in symmetry. In view of the known 1,10-phenanthroline complexes of the same metal ions, where as many as 4 chelates are associated, the present work indicates that the coordination number of the metal ion is strongly dependent on the intramol. N-N distance in the chelating heterocycle.
