Abstract: | The title compound Ni(napyo)2(H2O)2](NO3)2 was formed by the reaction of nickel(II) nitrate with 1,8-naphthyridine-N-monoxide (napyo) in ethanol medium. The complex crystallizes in the monoclinic, space groupP21/n withZ=2. Lattice parameters are:a=7.160(2),b=11.713(3),c=11.830(2) Å, =95.11(3)°. The structure was determined from 1399 observed reflections and refined toR=0.061. The Ni atom shows a slightly distorted octahedral coordination, being bonded to two oxygen atoms and two nitrogen atoms of two napyo ligands and to two oxygen atoms of two water molecules. |
