Abstract Four coordination polymers, namely, [Zn 2 (TIYM)(2,6‐PYDC) 2 ] n · n (CH 3 OH) · 3 n (H 2 O) ( 1 ), [Cu(TIYM)(2,6‐PYDC)] n · 3 n (H 2 O) ( 2 ), [Co(TIYM)(2,6‐PYDC)] n · n (CH 3 OH) · 3 n (H 2 O) ( 3 ), and [Cd 2 (TIYM)(2,6‐PYDC) 2 (H 2 O)] n · n (H 2 O) ( 4 ) with the flexible N‐containing ligand [tetrakis(imidazol‐1‐ylmethyl)methane (TIYM)] and the N‐containing dicarboxylic acid [2,6‐pyridinedicarboxylic acid (2,6‐PYDC)] were prepared. Compounds 1 – 4 show various structures because of different N–C center –N angles ( θ ) of TIYM ligands and changing coordination modes of 2,6‐PYDC. Compounds 1 , 2 , and 3 display a similar 1D ladder‐like chain, whereas 4 gives a 1D quad‐core lifting platform shaped belt. The structural diversities in 1 – 4 suggest that the multiple coordination modes or the different freely twist angles of ligands and the presence of different metal atoms play important roles in the resulting structures of the coordination polymers. Furthermore, the solid‐state luminescence properties of 1 and 4 , and the magnetic properties of 3 were investigated.
