Syntheses of Novel Coordination Polymers Using Bis-Imidazole Ligand Having Steric Hindrance and Methoxy Group

Three novel coordination polymers {[Cu2(bitbu-OMe)4(SO4)2]·6MeOH}n (1), {[Co2(bitbu-OMe)4(NCS)4]0.5·2DMF}n (2), {[Co(bitbu-OMe)2(NCS)2]·2MeOH}n (3) (bitbu-OMe = 1,1’-[(5-tert-butyl-2-methoxybenzene-1,3-diyl)dimethanediyl]bis(1H-imidazole)) are synthesized through a slow evaporation method using solvothermal technique of CuSO4·5H2O or Co(SCN)2 with bitbu-OMe. X-ray diffraction analysis results reveal that 1, 2, and 3 have similar two-dimensional layer networks. The study of the effect of the methoxy group in bitbu-OMe towards the stability of ligand conformation in obtained coordination polymers becomes necessary to be conducted in the future to unveil the reason for conformation similarity of ligand in coordination polymers.
