Crystal structure of ammonium bis(pyridine-2,6-dicarboxylato-κ(3) O,N,O′)chromate(III) from synchrotron data
The structure of the title compound, (NH(4))[Cr(pydc)(2)] (pydc is pyridine-2,6-dicarboxylate, C(7)H(3)NO(4)), has been determined from synchrotron data. The Cr(III) ion and the N atom of the ammonium cation are located on a crystallographic fourfold rotoinversion axis (-4). The Cr(III) cation is...

description | The structure of the title compound, (NH(4))[Cr(pydc)(2)] (pydc is pyridine-2,6-dicarboxylate, C(7)H(3)NO(4)), has been determined from synchrotron data. The Cr(III) ion and the N atom of the ammonium cation are located on a crystallographic fourfold rotoinversion axis (-4). The Cr(III) cation is coordinated by four O atoms and the two N atoms of two meridional pydc ligands, displaying a distorted octahedral geometry. The Cr—N and Cr—O bond lengths are 1.9727 (15) and 1.9889 (9) Å, respectively. The crystal structure is stabilized by intermolecular hydrogen bonds involving the N–H groups of the ammonium cation and pyridine C–H groups as donors and the non-coordinating carbonyl O atoms as acceptors. |
