Abstract Five novel coordination polymers, [(Cu(L 1 ) 2 OH) · Cl · 3H 2 O] ( 1 ) [L 1 = bis( N ‐imidazolyl)methane], [Cd(L 1 ) 2 (NCS) 2 ] ( 2 ), [Zn(L 1 ) 2 (NCS) 2 ] ( 3 ), [Cu(L 1 ) 2 (NO 3 ) 2 ] ( 4 ), and [Cu(L 2 ) 1.5 (NCS) 2 ] ( 5 ) [L 2 = 1,4‐bis( N ‐imidazolyl)butane] were obtained from self‐assembly of the corresponding metal salts with flexible ligands and their structures were fully characterized by X‐ray diffraction (XRD) analysis, Fourier Transform Infrared (FT‐IR) spectroscopy, elemental analysis and thermogravimetric (TGA) measurements. X‐ray diffraction analyses revealed that complexes 1 , 2 , 3 , and 4 exhibit 1D double‐stranded chain structures, which result from doubly bridged [CuOH], [ M (NCS) 2 ] ( M = Cd, Zn), and [Cu(NO 3 ) 2 ] units, respectively. The polymeric copper complex 5 displays 1D ladder structure., These complexes, with the exception of complex 1 , are stable up to 300 °C.
