Three d 10 ‐transition‐metal coordination compounds [Cd(tfpb) 2 (4‐bpmh)] n ( 1 ), [Cd(9‐aca)(NO 3 )(OHCH 3 )(4‐bpmh)] n ( 2 ) and [Zn 2 (dpp) 4 (4‐bpmh)] ( 3 ) with the bridging ligand 4‐bpmh were synthesized [4‐bpmh = 1,2‐bis(pyridin‐4‐ylmethylene)hydrazine, tfpb = 4,4,4‐trifluoro‐1‐phenylbutane‐1,3‐dionate, 9‐aca = anthracene‐9‐carboxylate, dpp = 1,3‐diphenylpropane‐1,3‐dionate]. Compounds 1 – 3 were characterized by FT‐IR spectroscopy, elemental analysis, and structurally authenticated by X‐ray crystallography. Compounds 1 – 3 are constructed by an O,O '‐donor ligand including chelating β‐diketonates (tfpb, dpp) in 1 and 3 and a carboxylate ligand (9‐aca) in 2 in combination with a linear neutral bidentate and bridging N‐ligand (4‐bpmh). The assembly and action of the bridging 4‐bpmh ligand leads to one‐dimensional coordination polymers in 1 , 2 and to a dinuclear coordination complex in 3 . The structures and the solid‐state supramolecular interactions for studying the crystal packing fashions of 1 – 3 were analyzed. The supramolecular interactions including hydrogen bonding, C–H ··· π, π ··· π, and C–F ··· π in 1 , 2 , and 3 were founded.
