Synthesis, crystal structure and Hirshfeld surface analysis of tetra-aqua-bis-(isonicotinamide-κN¹)cobalt(II) fumarate.

ABSTRACT: The reaction of cobalt(II) with fumaric acid (H₂fum) and isonicotinamide in a basic solution produces the title salt, [Co(C₆H₆N₂O)₂(H₂O)₄](C₄H₂O₄). In the complex cation, the Co^II atom, located on an inversion centre, is coordinated by two isonicotinamide and four water mol-ecules in a distorted N₂O₄ octa-hedral geometry. The fumarate anion is located on another inversion centre and is linked to neighbouring complex cations via O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds. In the crystal, the complex cations are further linked by O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular architecte
