Two trinuclear Ni(II) and Cu(II) coordination compounds [{Ni(L1)(C2H5OH)}2(μ-OAc)2Ni]·2C2H5OH (1) and [{Cu(L2)(CH3OH)}2(μ-OAc)2Cu]·2CH3OH (2) constructed from asymmetrical Salamo-type ligands H2L1 and H2L2 (H2L1 = 5-(N,Nʹ-diethylamino)-2,2ʹ-[ethylenediyldioxybis(nitrilomethylidyne)]diphenol and H2L2 = 2,2ʹ-[ethylenediyldioxybis(nitrilomethylidyne)]naphtholphenol) were synthesized and characterized by physicochemical and spectroscopic methods. Complex 1 is a centrosymmetrical trinuclear Ni(II) coordination compound. Three hexa-coordinated Ni(II) atoms have slightly distorted octahedral geometries. Complex 2 contains three hexa-coordinated Cu(II) atoms bearing distorted octahedral geometries too. In addition, the thermal analyses and Hirshfeld surfaces analyses of complexes 1 and 2 have been discussed in detail.
