Assembly reactions of 5-(isonicotinamido)isophthalic acid (H 2INAIP) with Ln2O3 orn(NO3) 3·6H2O together with NaOH in the presence of AgNO3 result in formation of two series of new 4d-4f heterometallic coordination polymers {[LnAg(INAIP)2]·3H2O} n [Ln = Nd (1), Sm (2), Eu (3), Gd (4), Tb (5)] and {[LnAg(INAIP)2(H2O)]·xH2O}n [Ln = La (6), Pr (7), Nd (8), x = 0; Dy (9), Er (10), x = 1]. The results of single-crystal X-ray diffraction analysis indicate that 1-5 are isomorphous and have 2-fold interpenetrated 3D structure with 3-nodal net Point ...
