Poly[[{μ₂-5-[(dimethylamino)(thioxo)methoxy]benzene-1,3-dicarboxylato-κ⁴ O ¹,O 1′:O ³,O 3′}(μ₂₋4,4′-dipyridylamine-κ² N ⁴:N 4′)cobalt(II)] dimethylformamide hemisolvate monohydrate]

In the crystal structure of the title compound, {[Co(C 11 H 9 NSO 5 )(C 10 H 9 N 3 )]0.5C 3 H 7 NO·H 2 O} n or {[Co(dmtb)(dpa)]·0.5DMF·H 2 O} n (dmtb 2– = 5-[(dimethylamino)thioxomethoxy]-1,3-benzenedicarboxylate and dpa = 4,4′-dipyridylamine), an assembly of periodic [Co(C 11 H 9 NSO 5 )(C 10 H 9 N 3 )] n layers extending parallel to the bc plane is present. Each layer is constituted by distorted [CoO 4 N 2 ] octahedra, which are connected through the μ 2 -coordination modes of both dmtb 2– and dpa ligands. Occupationally disordered water and dimethylformamide (DMF) solvent molecules are located in the voids of the network to which they are connected through hydrogen-bonding interactions.
