Abstract
2-Carbamoyl-4-nitrobenzoic acid (2-ca-4nbaH) has been prepared by alkaline hydrolysis of 4-nitrophthalimide. Aqueous reaction of MgCO 3 with 2-ca-4nbaH results in the formation of [Mg(H 2 O) 6 ](2-ca-4nba) 2 , which crystallizes in the centrosymmetric monoclinic space group P2 1 /c with Mg(II) situated on an inversion center. The crystal structure consists of a distorted octahedral hexaaquamagnesium(II) cation and a free uncoordinated 2-ca-4nba anion. The cation and anion are involved in three varieties of H-bonding interactions, resulting in a supramolecular bilayer of 2-ca-4nba anions sandwiched between layers of [Mg(H 2 O) 6 ] 2+ cations.
