, consists of the halves of the centrosymmetric macrocyclic cation and the C
2-symmetric dicarboxylate dianion and of the water molecule of crystallization. The Ni2+ ion is coordinated by the four secondary N atoms of the macrocyclic ligand characterized by the most energetically favourable trans-III conformation and two mutually trans O atoms of the carboxylate, forming a slightly tetragonally elongated trans-N4O2 octahedron. The crystals are composed of parallel polymeric chains of the macrocyclic cations linked by the anions of the acid running along the [101] direction. Each polymeric chain is bonded to four neighbouring ones via water molecules providing O—H...O hydrogen bonds to the non-coordinated carboxyl O atoms to form a three-dimensional supramolecular network.
