Four double‐strand one‐dimensional (1D) coordinationpolymers, namely, {[Ni(N3Py) 2 (NO 3 ) 2 ] · (C 6 H 6 ) x · C 2 H 5 OH} n ( 1 ), [Cd(ImBNN) 2 (CH 3 C 6 H 4 SO 3 ) 2 ] n ( 2 ), {[Co(N3OPy) 2 (H 2 O) 2 ](ClO 4 ) 2 · C 6 H 6 · H 2 O} n ( 3 ), and {[Co(N3OPy) 2 (H 2 O) 2 ](ClO 4 ) 2 · (C 8 H 10 ) x } n ( 4 ) were obtained from the assembly of three N , N′ ‐type Schiff base ligands, 1,4‐bis(3‐pyridyl)‐2,3‐diaza‐1,3‐butadiene (N3Py), 2,5‐bis(4′‐(imidazol‐1‐yl)benzyl)‐3,4‐diaza‐2,4‐hexadiene (ImBNN), and bis[4‐(3‐pyridylmethylenemino)phenoxy]methane (N3OPy), with transition‐metal ions. All complexes were characterized by single‐crystal X‐ray diffraction, X‐ray powder diffraction, and FTIR measurements. The guest‐inclusion behavior of these complexes were investigated by thermogravimetric and X‐ray powder diffraction analyses. The structural relationship between the ligands and the cavity sizes and packing fashions have been discussed to elucidate the distinctive guest‐inclusion behavior of these complexes.(© Wiley‐VCH Verlag GmbH & Co.
