چکیده
The title compound, [Co(C24H28N2O6)] n , crystallizes as infinite chains related to one another by inversion centers, giving a centrosymmetric coordination polymer. The Co(II) ion, situated on a twofold rotation axis, forms a complex with the crown-4 moiety of the 3,3'-[(1,7-dioxa-4,10-di-aza-cyclo-do-decane-4,10-di-yl)bis-(meth-ylene)]dibenzoate anion. The dis-torted octahedral coordination sphere of the Co(II) ion is completed by two carboxyl-ate O atoms from two bridging intra-chain ligands. Metallomacrocyclic rings of 16 atoms are present, with each ring containing two Co(II) ions and 14 atoms from the bridging ligands. These units repeat as infinite zigzag chains along [101].

The title coordination polymer, {[Co(C(18)H(14)O(4))(C(10)H(8)N(2))]·0.5H(2)O}(n), features a helical polymeric chain that runs along the b axis. The Co atoms are chelated by the carboxyl-ate groups of two 3,3'-(but-2-ene-2,3-di-yl)dibenzoate ligands and the N atoms of a 2,2'-bipyridine ligand. The lattice water mol-ecule is disordered about a center of inversion and is connected to the chain b...
