Four novel divalent transitional metal succinates (suc) with 4‐aminopyridine (apy), [ M (apy) 2 (H 2 O) 2 (μ‐suc)] n [ M = Ni ( 1 ), Co ( 2 )] and [ M (apy) 2 (H 2 O)(suc)] [ M = Cu ( 3 ), Zn ( 4 )] were synthesized and characterized by elemental analyses, IR spectroscopy, and TG‐DTA analyses. The single‐crystal X‐ray analysis of 1 revealed that it crystallizes in the orthorhombic space group Pcab and that it is a 1D coordination polymer. The suc molecule acts as a bis‐monodentate bridging ligand whereas apy coordinates to the Ni II ions only through its pyridine nitrogen atoms. The chains are connected by OH–O hydrogen bonds into 2D networks. Compound 4 emits intense fluorescence at 380 nm and intense violet fluorescence at 418 nm, upon excitation at 310 and 350 nm, respectively.
