Cover illustration: The asymmetric unit of the three-dimensional metal–organic hybrid compound poly[bis­(μ2-N,N-di­methyl­formamide-κ2O:O)bis­(μ4-thio­phene-2,5-di­carboxyl­ato-κ4O:O′:O′′:O′′′)dicobalt(II)], [Co2(C6H2O4S)2(C3H7NO)2]n, comprises two cobalt(II) cations, one residing on a twofold axis and the other on a centre of inversion, one thio­phene-2,5-di­carboxyl­ate (tdc2−) ligand and one coordinating di­methyl­formamide (DMF) solvent mol­ecule. Both of the cobalt(II) cations exhibit an octa­hedral coordination environment from the four carboxyl O atoms of the tdc2− anions in a μ4-κ1:κ1:κ1:κ1 fashion and two O atoms from DMF. A pair of carboxyl O atoms and one DMF molecule connect the adjacent cobalt(II) cations into an infinite chain, leading to a rod-spacer framework with rhombus-window channels, yet no residual solvent-accessible voids are present because the coordinating DMF molecules are oriented into the potential channels. See: Ren, Huang, Yin & Cao [IUCrData (2022). 7, x220775].

The title compound has an iron–gallium bond distance of 2.3028 (3) Å. The gallium atoms are connected by two bridging chlorine atoms, each gallium also has one terminal chlorine. The mol­ecule has an inversion center located between the gallium atoms. The cyclo­penta­dienyl ligand was modeled for disorder.
