摘要

The reaction of CoCl2 with succinic acid and isonicotinamide in basic solution produces the title complex [Co(C6H6N2O)2(H2O)4](C4H4O4). The cobalt(II) ion of the complex cation and the succinate anion are each located on an inversion centre. The CoII ion is octa­hedrally coordinated by four O atoms of water mol­ecules and two N atoms of isonicotinamide mol­ecules. The two ions are linked via Owater—H⋯Osuccinate hydrogen bonds, forming chains propagating along [001]. In the crystal, these hydrogen-bonded chains are linked into a three-dimensional framework by further O—H⋯O hydrogen bonds and N—H⋯O hydrogen bonds. The framework is reinforced by C—H⋯O hydrogen bonds. Hirshfeld surface analysis and two-dimensional fingerprint plots have been used to analyse the inter­molecular inter­actions present in the crystal.
