Summary: Two novel homomultinuclear complexes were synthesized and characterized with a newly designed rigid bis(salamo)-type tetraoxime ligand. Complex 1 is a symmetrical six-core cluster structure with Co(II) atoms sandwiched between the ligands, while complex 2 has a dinuclear structure with Ni(II) atoms located in the N2O2 cavities of the ligand. The coordination ratios were determined by studying the fluorescence properties, showing different metal to ligand binding ratios for each complex.

Summary: An unexpected mono-nuclear Cu(II) complex [Cu(L-1)] was synthesized using a new ligand H2L1 and Cu(II) acetate. The crystal structure analysis confirmed that the Cu(II) complex is obtained from the reaction with the ligand H2L1, not the original ligand H3L. Quantum chemical calculations revealed that the energy gap of the Cu(II) complex is reduced compared to the ligand due to orbital combination.

Summary: A di-nuclear salamo-Zn(II) complex [Zn2(L) Cl2] (1) was synthesized using a salamo-type ligand H2L containing a bare formyl group. A new ligand H2L' was produced through the destruction of the O4 coordination environment of the H2L ligand in the presence of the Claisen-Schmidt reaction catalyzed by triethylamine. This led to the self-assembly reaction and the formation of a tetra-nuclear salamo-Ni(II) complex [Ni4(L ')2(mu 2-Cl)2(mu 3-OMe)2(EtOH)2] (2).
