• In this study, we obtained new bridged type [M(3AP)2Ni(μ-CN)2(CN)2]n complexes (M = Co and Cu).
• Then we recorded FT-IR, FT-Raman and powder XRD spectra of these complexes.
• In addition, we made elemental and thermal analysis of these complexes.
• Moreover, the obtained the data is discussed.
Two novel cyano-bridged heteropolynuclear complexes, [Co(3-aminopyridine)2Ni(μ-CN)2(CN)2]n and [Cu(3-aminopyridine)2Ni(μ-CN)2(CN)2]n have been synthesized and characterized by elemental, thermal, FT-IR and FT-Raman spectroscopies. The structures of complexes have been determined by X-ray powder diffraction. The FT-IR and FT-Raman spectra of complexes have been recorded in the region of 3500–400 cm−1 and 3500–100 cm−1, respectively. General information was acquired about structural properties of these complexes from FT-IR and FT-Raman spectra by considering changes at characteristic peaks of the cyano group and 3AP. The splitting of the ν(CN) stretching bands in the FT-IR spectra for complexes indicates the presence of terminal and bridging cyanides. The thermal behaviors of these complexes have been also investigated in the range of 25–950 °C using TG and DTG methods. Magnetic susceptibility measurements were made at room temperature using Gouy-balance.
