Hendricker, D. G. published the artcileComplexes of 1,8-naphthyridines. VIII. Complexes of 2,7-dimethyl-1,8-naphthyridine with rare earth nitrates, Formula: C10H10N2, the publication is Journal of Inorganic and Nuclear Chemistry (1972), 34(6), 1949-54, database is CAplus.
Rare earth nitrate complexes of the type M(2,7-dmn-apy)2(NO3)3 (M = Y, La-Yb 2,7-dmnapy = 2,7-dimethyl-1,8-naphthyridine) were synthesized. The compounds were characterized by elemental analyses, molar conductances, magnetic moments, and ir (4000-200 cm-1). The molar conductance and ir spectral data show that all nitrate groups are coordinated to the metals. From this and crystallographic data of an analogous compound the complexes appear to be ten-coordinate.
