We report a symmetry-breaking effect in the family of coordination polymers, Ln III (4, 4'-bipyridine- N, N '-dioxide) 2 (OH 2) 4 Co III (CN) 5 (NO 2) •2H 2 O (Ln = La-Nd, Sm), induced by uncommon pentacyanidocobaltate linkers bearing nitrito- κ N ligands. Resulting structural polarity leads to a. . .
