The cationic complex [Ni(neoc)2(NO3)]+ with NO3- (1), TCNQ- (3), or (TCNQ-TCNQ)2- (4) as counterions, and the neutral complex [Ni(neoc)([NO3]- -κ1O)([NO3]- -κ2O,O´)(H2O)] (2) can be obtained from different reactions involving Ni(II), neoc, NO3- and TCNQ. The molecular and extended crystal structure of compound 2, which displays two different coordination modes for NO3- , are compared to those of the analogous Mn, Fe and Co compounds, revealing a correlation between the coordination geometry of the nominally monodentate nitrato ligand and the covalent radius of the central metal atom. Despite the differences in molecular geometry, the extended structures of the Ni (2) and Mn compounds are similar to each other but different from those of the Fe and Co complexes, which are similar to each other.
