ABSTRACT: To investigate the effect of the polycarboxylates and metal ions on the assembly and structures of complexes based on a thiophene-containing bis-pyridyl-bis-amide N,N'-bis(pyridine-3-yl)thiophene-2,5-dicarboxamide (3-bptpa) ligand, nine 0D → 3D complexes of [Ni2(3-bptpa)4(1,2-BDC)2(H2O)2] (1), [Ni(3-bptpa)(IP)(H2O)2]·H2O (2), [Ni(3-bptpa)(5-MIP)(H2O)2]·H2O (3), [Ni(3-bptpa)(5-NIP)(H2O)] (4), [Ni(3-bptpa)(5-AIP)]·2H2O (5), [Ni2(OH)(3-bptpa)(1,3,5-BTC)]·DMA·5H2O (6), [Cu(3-bptpa)(5-MIP)]·3H2O (7), [Cu(3-bptpa)(5-AIP)(H2O)0.25]·H2O (8), and [Cu(3-bptpa)(1,3,5-HBTC)] (9) (1,2-H2BDC = 1,2-benzenedicarboxylic acid, H2IP = 1,3-benzenedicarboxylic acid, 5-H2MIP = 5-methylisophthalic acid, 5-H2NIP = 5-nitroisophthalic acid, 5-H2AIP = 5-aminoisophthalic acid, DMA = N,N'-dimethylacetamide, and 1,3,5-
