•Two new heterometallic complexes have been synthesized by solvothermal method.•The stereospecific blockade of the ligands in the synthesis system seems to be the most important synthetic parameter.•The magnetism studies show that 1 and 2 exhibit ferromagnetic interactions.•Complex 1 shows slowing down of magnetization and not blocking of magnetization.
Using the solvothermal method, we present the comparative preparation of {[Co3Na(dmaep)3(ehbd)(N3)3]·DMF}n (1) and [Co2Na2(hmbd)4(N3)2(DMF)2] (2), where Hehbd is 3-ethoxy-2-hydroxy-benzaldehyde, Hhmbd is 3-methoxy-2-hydroxy-benzaldehyde, and Hdmaep is 2-dimethylaminomethyl-6-ethoxy-phenol, which was synthesized by an in-situ reaction. Complexes 1 and 2 were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Complex 1 is a novel heterometallic cluster-based 1-D chain and 2 is a heterometallic tetranuclear cluster. The {Co3IINa} and {Co2IINa2} cores display dominant ferromagnetic interaction from the nature of the binding modes through μ1,1,1-N3– (end-on, EO).
Graphical abstractTwo novel cobalt complexes have been prepared. Compound 1 consists of tetranuclear {Co3IINa} units, which further formed a 1-D chain. Compound 2 is heterometallic tetranuclear cluster. Two complexes display dominant ferromagnetic interaction.Figure optionsDownload full-size imageDownload as PowerPoint slide
