Summary of main observation and conclusion This work presents the synthesis, crystal structure and properties of a novel noncentrosymmetric (NCS) coordination polymer (CP), namely, (Me 2 NH 2 ) 3 [BaLi(2,6‐PyDC) 3 (H 2 O)] ( 1 ) (2,6‐PyDC = pyridine‐2,6‐dicarboxylate acid), which represents the first example of BaLi‐CPs with 2,6‐PyDC ligand. Single‐crystal X‐ray structural analysis reveals that the compound features a two‐dimensional (2D) layered structure. The simplified structure of each layer belongs to the hcb topology. The second harmonic generation (SHG) response of 1 is about 0.5 times that of KH 2 PO 4 (KDP) marker. What is more, 1 emits bright blue light upon the excitation of 365 nm UV light with the quantum yield (QY, Φ ) of 1.63%. The successful construction of this compound convinces the feasibility of constructing NCS CPs via the combination of [BaL 3 ] unit and Li(I) ion.
