•We conducted reactions of aliphatic diamines with Co(II) tri-tert-butoxysilanethiolate.•Mononuclear compound as well as 1D coordination polymers have been obtained.•Complexes have been characterized with the use of X-ray diffraction, FT-IR, TGA, DSC.•Crucial implications of H-bonding interactions on final topology of polymeric chains.
Four Co(II) complexes, [Co{SSi(OtBu)3}2(dmpda)] 1, [Co{SSi(OtBu)3}2(bda)2]n2 [Co{SSi(OtBu)3}2(pda)2]n3 and [Co{SSi(OtBu)3}2(hda)2]n4 [dmpda = 3-(dimethylamino)-1-propylamine; bda = 1.4-butanediamine; pda = 1.5-pentanediamine; had = 1.6-hexanediamine] have been synthesized and characterized using X-ray diffraction. Complex 1 is mononuclear and contains Co(II) coordinated by dmpda molecule in chelating mode, whereas compounds 3 and 4 are one-dimensional polymers with pda and hda diamines as bridges between the metallic centers respectively. In all complexes tri-tert-butoxysilanethiolate residue acts as terminal S-donor ligand. Full characterization of obtained compounds 1–4 was additionally carried out with the use of IR and UV–vis spectroscopy, elemental and thermal analysis.
