Abstract:
The crystal structure of [Ni(bipy)(2)(ONO(2))(2)] x2(pyrene), poly[[[bis(nitrato-O)nickel(II)]bis(mu-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 P2(1)/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.
