Piperidinium bis(2-oxidobenzoato-kappa O-2(1),O-2)borate

The asymmetric unit of the title compound, C5H12N+center dot-C14H8BO6- or [C5H12N][BO4(C7H4O)(2)], contains two piperidinium cations and two bis(salicylato) borate anions. The coordination geometries around the B atoms are distorted tetrahedral. In the two molecules, the aromatic rings are oriented at dihedral angles of 76.27 ( 3) and 83.86 ( 3)degrees. The rings containing B atoms have twist-boat conformations, while the two cations adopt chair conformations. In the crystal, the component species are linked by N-H center dot center dot center dot O hydrogen bonds. In the crystal structure, intra- and intermolecular N-H center dot center dot center dot O hydrogen bonds link the molecules.
