Abstract: The crystal structure of [Ni(bipy)2(ONO2)2]·2(pyrene), poly[[[bis(nitrato-O)nickel(II)]bis(![[bold mu]](/logos/entities/mu_bdgif.gif)
-4,4'-bipyridyl-N,N'] bis(pyrene)], was originally reported in space group Pn [Biradha et al. (1999). Chem. Commun. pp. 1327-1328]. Reasons are given for changing the space group to P21/n. Consequently, incorrect descriptions of the title compound in the literature must be altered. In particular, the structure is not polar. It is further contended that description in terms of `complementary, interpenetrating covalent and noncovalent two-dimensional networks' is misleading as the `noncovalent network' (of pyrenes) has geometrical but not physical significance. The title compound is a typical host-guest inclusion complex.
