The O atom, the aldehyde H atom and the benzene ring of one of the FB anions are disordered over two positions. The O atoms were freely refined [refined occupancy ratio 0.79\u2005(2):0.21\u2005(2)], while the aldehyde H atoms and the benzene ring atoms were refined with fixed occupancy ratios of 0.8:0.2 and 0.5:0.5, respectively. In the ordered FB anion, the carboxylate group is twisted away from the attached benzene ring (<jats:italic>A<\/jats:italic>) by 22.7\u2005(8)\u00b0. In the disordered FB anion, the corresponding angles are 15.6\u2005(10) and 11.4\u2005(11)\u00b0 for rings<jats:italic>B<\/jats:italic>and<jats:italic>B<\/jats:italic>\u2032, respectively. Benzene rings<jats:italic>A<\/jats:italic>and<jats:italic>B<\/jats:italic>are oriented at a dihedral angle of 24.2\u2005(7),<jats:italic>A<\/jats:italic>and<jats:italic>B<\/jats:italic>\u2032 at 43.0\u2005(8)\u00b0. The pyrazine ring makes dihedral angles of 67.5\u2005(4), 89.6\u2005(7) and 86.2\u2005(7)\u00b0, respectively, with benzene rings<jats:italic>A<\/jats:italic>,<jats:italic>B<\/jats:italic>and<jats:italic>B<\/jats:italic>\u2032. The pyrazine ligands bridge the Cd<jats:sup>II<\/jats:sup>cations, forming polymeric chains running along the<jats:italic>b<\/jats:italic>-axis direction. In the crystal, O\u2014H<jats:sub>water<\/jats:sub>... O<jats:sub>carboxylate<\/jats:sub>hydrogen bonds link adjacent chains into layers parallel to the<jats:italic>bc<\/jats:italic>plane. These layers are linked<jats:italic>via<\/jats:italic>C\u2014H<jats:sub>pyrazine<\/jats:sub>... O<jats:sub>formyl<\/jats:sub>hydrogen bonds, forming a three-dimensional network. \u03c0\u2013\u03c0 interactions [centroid\u2013centroid distances = 3.870\u2005(11)\u20133.951\u2005(5)\u2005\u00c5] further stabilize the crystal structure.
