Three solid-state chemical reactions are described, which yield products that are expected to be unattainable by other means. The reactions take place in molecular crystals of orotate or citrate complexes of cobalt.  In one of the citrate complexes, the polymeric {Cs2 [Co7(C6H4O7)4(H2O)13.5]�7.5H2O}n, 1  , reaction occurs with cross-linking to form a two-dimensional polymer with a seven-coordinate Co(II) at the point of cross-linking.  In the second Co(II) citrate system, a sub-periodic crystal formed by the unsymmetrical cubane-based complex {[Co(H2O)4]3[Co(H2O)5]Co4(citr)4}�7H2O, 2  , reacts to form a symmetrical complex 3  , at the same time conferring homogeneous periodicity on the crystal. A cationic one-dimensional-polymeric Co(III) orotate compound, {[Co(orotate)2(bipy)][Cu(H2O)(bipy)]}n(n+) 4a  , undergoes a topotactic reaction in which it incorporates its counterion, [Co(orotate)2(bipy)](-), 4b  , as a metaloligand to form a neutral one-dimensional polymer {[Cu(bipy)][Co(orot)2(bipy)][�-Co(orot)2(bipy)]}n, 5  , with two Co centers per link.
