Synthesis, Structures, and Properties of Four Novel Coordination Compounds based on a Flexible Tetrakis(imidazol‐1‐ylmethyl)methane Ligand

Abstract

Four coordination polymers, namely, [Zn 2 (TIYM)(2,6-PYDC) 2 ] n ·n(CH 3 OH)·3n(H 2 O) (1), [Cu(TIYM)(2,6-PYDC)] n ·3n(H 2 O) (2), [Co(TIYM)(2,6-PYDC)] n ·n(CH 3 OH)·3n(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 chang-* Prof. Dr. L. Du
