Crystal structure of bis­(4-acetyl­anilinium) tetra­chlorido­cobaltate(II)

The structure of the title salt, (C(8)H(10)NO)(2)[CoCl(4)], is isotypic with the analogous cuprate(II) structure. The asymmetric unit contains one 4-acetyl­anilinium cation and one half of a tetra­chlorido­cobaltate(II) anion for which the Co(II) atom and two Cl(−) ligands lie on a mirror plane. The Co—Cl distances in the distorted tetra­hedral anion range from 2.2519 (6) to 2.2954 (9) Å and the Cl—Co—Cl angles range from 106.53 (2) to 110.81 (4)°. In the crystal, cations are self-assembled by inter­molecular N—H⋯O hydrogen-bonding inter­actions, leading to a C(8) chain motif with the chains running parallel to the b axis. π–π stacking inter­actions between benzene rings, with a centroid-to-centroid distance of 3.709 Å, are also observed along this direction. The CoCl(4) (2−) anions are sandwiched between the cationic chains and inter­act with each other through inter­molecular N—H⋯Cl hydrogen-bonding inter­actions, forming a three-dimensional network structure.
