Assembly reactions of pyridyl- and carboxylate-containing ligand 5-(isonicotinamido)isophthalic acid (H2INAIP) with corresponding metal salts result in formation of six new coordination polymers, namely {[Mn(INAIP)(DMF)]·0.5DMF}n (1), {[Mn(INAIP)(H 2O)2]·4H2O}n (2), {[Co(INAIP)(H2O)]·2H2O}n (3), {[Co(INAIP)(bpy)0.5]}n (4), {[Co(INAIP)(Him)(H 2O)]·H2O}n (5), and {[Cu(INAIP)(Him) (H2O)]·H2O}n (6) (DMF = N,N-dimethylformamide, bpy = 4,4′-bipyridine, Him = imidazole). The results of single-crystal X-ray diffraction analysis indicate that 1 is...
