摘要

1′-Amino­cobaltocenium-1-carb­oxy­lic acid chloride, [Co(C5H6N)(C6H5O2)]Cl·H2O, (>3), and its azo derivative 1′-[2-(1-amino-2,6-dimethylphenyl)diazen-1-yl]cobaltocenium-1-carb­oxy­lic acid hexa­fluorido­phosphate, [Co(C13H14N3)(C6H5O2)]PF6·H2O (>5) were obtained from cobaltocenium-1,1′-di­carb­oxy­lic acid hexa­fluorido­phosphate by converting one carboxyl group to its chloro­carboxyl derivative followed by chloride/azide exchange, Curtius rearrangement, diazo­tiation and azo coupling with 2,6-di­methyl­aniline. Both title compounds crystallize as their monohydrates. In the crystal structure of >3, both functional groups lie in the same direction, with the Cp rings being nearly eclipsed, and participate in an extended hydrogen-bonded supra­molecular network including the counter-ion and the water mol­ecule of crystallization. Although the functional groups in >5 are somewhat further apart, bearing a greater torsion angle with the Cp rings now staggered, a similar supra­molecular network is observed with not only the carb­oxy­lic acid and azo groups, but also with the more remote amino group participating in a hydrogen-bonded network, again including the counter-ion and the water mol­ecule. The hexa­fluorido­phosphate ion shows positional disorder. Compound >3 was refined as an inversion twin. In >5, each of the six F atoms is disordered over two sets of sites in a 1:1 ratio.
