Acetate‐bridged binuclear Co(II) and Ni(II) complexes, [Co2(L)(μ‐OAc)(EtOH)] (1) and [Ni2(L)(μ‐OAc)(EtOH)] (2) were synthesized via the reaction of a new bis(salamo)‐like ligand with two different metal(II) acetates. X‐ray single crystal diffraction analyses showed that two metal(II) ions (Co or Ni) occupy two sets of N2O2 cavities, respectively. The acetate group bridges the two metals, and the ethanol oxygen atom participates in the coordination. Furthermore, UV–vis titration experiments clearly indicated that the complexation between H3L and M(II) ions leads to the 1:2 complexes [(L)M2]+ through a highly synergistic process. Bond valence sum (BVS) calculations exhibited that the Co(II) and Ni(II) ions are divalent. Secondly, the ligand H3L highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO‐LUMO) gap analysis and surface electrostatic potential were theoretically analyzed by theoretical calculation (density functional theory), and the reactivity of M(II) ions and the ligand in the complex formation process was demonstrated. Finally, the microscopic properties of the complexes were deeply understood through the calculation of the weak intramolecular interactions and the unstressed regions outside the complexes.

A salamo‐type biscompartmental ligand was successfully prepared. On this basis, two novel pentanuclear zinc (II) salamo‐type complexes possessing solvent effect were self‐assembled successfully with different zinc (II) salts: [Zn5(L)2(μ‐OAc)2(CH3COCH3)] (1) and [Zn5(L)2(μ‐OAc)2(CH3CN)] (2). Complex 1 contains two fully deprotonated (L)4− units, five Zn(II) atoms, two coordinating acetate anions, and one coordinating acetone molecule. The zinc (II) atoms are all in a slightly distorted triangular bipyramidal geometrical configurations. Complex 2 consists of two fully deprotonated (L)4− units, five zinc (II) atoms, two coordinating acetate anions and a coordinating acetonitrile molecule. The different structures of the self‐assembling complexes may be attributed to various solvent effects applied in the self‐assembly. As a result, the acetate anions are involved in bridging coordination, thereby expanding the distance between secondary building units (SBUs). In addition, polar nonprotonic solvents, especially acetonitrile and acetone molecules, were involved in the coordination process. Finally, the reaction sites and intermolecular interactions were further discussed by MEP, IRI, and Hirshfeld surfaces, and their fluorescence properties were explored.
