One trinuclear Co(II) coordination compound [{CoL1(OAc)(CH3COCH3)}2Co] (1) and one unprecedented mononuclear Ni(II) coordination compound [Ni(L2)2] (2), constructed from a Salamo-type ligand H2L1 were synthesized and characterized by elemental analyses, IR, UV-vis spectra, and single crystal X-ray diffraction analyses. The results show that the Co(II) atoms have no significant distortion in CoO6 or CoO4N2 octahedrons in coordination compound 1. Interestingly, in coordination compound 2, the desired tri- or mono-nuclear Salamo-type Ni(II) coordination compound was not obtained, but an unprecedented Ni(II) coordination compound [Ni(L2)2] was synthesized, the Ni1 atom having no significant distortion in the NiO2N2 planar quadrilateral geometry. Furthermore, the antimicrobial activities of coordination compound 1 and previously reported coordination compound [{CoL1(OAc)(MeOH)}2Co]·2MeOH (3) are discussed. View Full-Text
