Three rare heteromultinuclear complexes, ∞ [NiL(4,4′‐bipy)Pr (NO 3 ) 3 ]·(CH 3 ) 2 CHOH ( 1 ), [{CuLSm (NO 3 ) 3 } 2 (4,4′‐bipy)]·CH 3 OH ( 2 ) and [{CuL (CH 3 CH 2 OH)Eu (NO 3 ) 3 ] ( 3 ) with a symmetrical salamo‐like hexadentate ligand H 2 L have been synthesized, and characterized by FT‐IR, UV–vis and X‐ray crystallography. Complex 1 is a 1D coordination polymer constructed from heterobimetallic [Ni(L)Pr (NO 3 ) 3 ] units which are connected by the exo‐dentate ligand 4,4′‐bipy bearing nitrogen‐donor atoms. Complex 2 is a heterotetranuclear dimer based on [Cu(L)Sm (NO 3 ) 3 ] moieties which are linked through the exo‐dentate 4,4′‐bipy hasing nitrogen‐donor atoms. Complex 3 is a heterodinuclear structure, Cu (II) atom is five‐coordinate possessing a distorted square pyramidal geometry, and Eu (III) atom is a deca‐coordinate adopting a distorted bicapped square antiprism. In addition, fluorescence and antimicobial properties of the ligand H 2 L and its complexes 1 – 3 have also been discussed.
