The white-light emission of a triple-component lanthanide coordination polymer turns to blue and red upon adding Mn and Ag ions, respectively.

A rare SCSC transformation for lanthanide coordination polymers is triggered by solvent-mediated isomerization.

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.042; wR factor = 0.095; data-to-parameter ratio = 10.5.In the anion of the title salt, C 6 H 16 N + ÁC 18 H 13 O 8 À , one of the carboxyl groups is deprotonated. Its O atoms are involved in intermolecular hydrogen bonding with the carboxyl group of an adjacent anion and the amino group of an adjacent cation. The two benzoyloxy rings are oriented with respect to each other at a dihedral angle of 79.46 (6) . Related literature
