Helical Coordination Polymers Based on Keggin-type POMs and N-donor Ligand

Two new 1D helical coordination polymers based on polyoxometalate were synthesized by self‐assembly of Keggin‐type POMs and copper salts in the presence of triangular N‐heterocyclic derivatives or long‐chain N‐containing carboxylate ligand, that are, (H 3 O)[{Cu(H 2 tpim) 2 }{SiMo 12 O 40 }] · 0.5H 2 O [Htpim = 2,4,5‐tri(4‐pyridyl)‐imidazole] ( 1 ) and [Cu 2 (Hcpp) 3 (cpp)(H 2 O)][PMo 12 O 40 ] · 2H 2 O [Hcpp = 1‐(4‐cyanobenzyl)‐3–2‐yl)pyrazole]...
