• The complex [Co(napyo)<SUB>2</SUB>(H<SUB>2</SUB>O)<SUB>2</SUB>](NO<SUB>3</SUB>)<SUB>2</SUB> was formed by the reaction of cobalt(II) nitrate with 1,8-naphthyridine 1-oxide (napyo) in methanol medium. The complex crystallizes in the monoclinic system, space group <I>P</I>2<SUB>1</SUB>⁄<I>n</I> with <I>Z</I>=2. Lattice parameters are: <I>a</I>=7.165(2), <I>b</I>=11.797(2), <I>c</I>=11.830(3) Å, β=95.14(3)°, <I>V</I>=995.9(4) Å<SUP>3</SUP>, <I>D</I><SUB>c</SUB>=1.705 g cm<SUP>−3</SUP>, <I>D</I><SUB>O</SUB>=1.714 g cm<SUP>−3</SUP>, λ(Mo <I>K</I>α)=0.71069 Å, μ=9.26 cm<SUP>−1</SUP>, <I>F</I>(000)=522. The final <I>R</I>=0.036 for 1433 unique observed reflections. Co<SUP>2+</SUP> ion is coordinated by two nitrogen atoms and four oxygen atoms to form a distorted octahedron.
