In the anion, the CoII centre is coordinated by the N atoms of four NCS ligands in a distorted tetrahedral geometry. In the complex cations, the NaI centre is coordinated by five O atoms of the 2,3-naphtho-15-crown-5 ligand and one water O atom. The complex molecules form a two-dimensional network via weak O¡ªH...S interactions between adjacent cations and anions %U http://scripts.iucr.org/cgi-bin/paper?S1600536809038641
