Metal and Ligand Effects on the Construction of Divalent Coordination Polymers Based on bis-Pyridyl-bis-amide and Polycarboxylate Ligands.

ABSTRACT: Ten coordination polymers constructed from divalent metal salts, polycarboxylic acids, and bis-pyridyl-bis-amide ligands with different donor atom positions and flexibility are reported. They were structurally characterized by single-crystal X-ray diffraction. The ten coordination polymers are as follows: (1) {[Ni(L¹)(3,5-PDA)(H₂O)₃]·2H₂O}_n (L¹ = N,N'-di(3-pyridyl)suberoamide, 3,5-H₂PDA = 3,5-pyridinedicarboxylic acid); (2) {[Ni₂(L¹)₂(1,3,5-HBTC)₂(H₂O)₄]·H₂O}_n (1,3,5-H₃BTC = 1,3,5-benzenetricarboxylic acid); (3) {[Ni(L²)(5-tert-IPA)(H₂O)₂]·2H₂O}_n (L² = N,N'-di(3-pyridyl)adipoamide, 5-tert-H₂IPA = 5-tert-butylisophthalic acid); (4<
