Two novel tetra‐ and hepta‐nuclear Ni(II) salamo‐type clusters, [Ni4(L)2(μ2‐Cl)2(μ3‐OH)2(EtOH)2]⋅4CH2Cl2 (1) and [Ni7(L)3(μ3‐OEt)2(μ3‐OH)6(EtOH)2] (2), were constructed by modulating different anions (Cl− and NO3−). X‐ray crystallographic researches revealed that cluster 1 is a tetranuclear cluster consisting of a symmetric binuclear structure in which chloride ions are involved in coordination. Although cluster 2 consists of seven Ni(II) ions, three deprotonated (L)2− parts, two μ3‐ethoxy groups, six μ3‐OH− anions, and two coordinated ethanol molecules, in which it is quite rare for a large number of water molecules to be deprotonated to participate in the bridging of the cluster due to the alkaline environment. TEM electron scanning displayed the distinct shapes. Comparison of DFT calculations revealed that cluster 2 is less chemically reactive and more kinetically stable, which is in accordance with the analytical results of weak interactions, where the stronger weak interaction forces were presented, the more stable the molecule is. Finally, a comparative analysis of UV–Vis, IR, and fluorescence spectra were carried out.

A novel complex [Zn II 3 L 2 ] 6+ was designed and then synthesized by using subcomponent self-assembly of zinc trifluoromethanesulfonate (Zn(OTf) 2 ), 2,4,6-tri(3-aminophenoxy) triazine, and 2-formylpyridine in CH 3 CN solution. The target compound's structure as a sandwich-like helicate was verified by 1 H NMR and ESI-MS measurements, and the hostguest interactions between the complex and a number of guest molecules were investigated. It was discovered that the effect of the host-guest interaction significantly changed when the aldehyde component was replaced by 3-methylpyridine-2-carboxaldehyde, which suggested that the guest-binding sites may occur around the peripheral apertures of the complex. Also the binding behavior of the tetraphenylborate guests was further investigated, which quantified the host-guest stoichiometry in the ratio of 1:2.
