Two new acylamide metal–organic frameworks (MOFs), based on mixed N ‐ and O ‐donor ligands, with 4‐connected topologies have been obtained, namely poly[[μ 2 ‐ N 1 , N 4 ‐bis(pyridin‐3‐yl)terephthalamide]bis(μ 3 ‐4,4′‐oxydibenzoato)dizinc(II)], [Zn 2 (C 14 H 8 O 5 ) 2 (C 18 H 14 N 4 O 2 )] n , (1), and poly[[(μ 2 ‐benzene‐1,4‐dicarboxylato)[μ 2 ‐ N 4 , N 4′ ‐bis(pyridin‐3‐yl)‐[1,1′‐biphenyl]‐4,4′‐dicarboxamide]dicadmium(II)] dihydrate], {[Cd(C 8 H 4 O 4 )(C 24 H 18 N 4 O 2 )]·2H 2 O} n , (2). Complex (1) is a 4‐connected CdSO 4 net with no interpenetration, where the Zn II cation is regarded as a 4‐connecting node with square geometry. Complex (2) is a 4‐connected dia net with threefold interpenetration, where the Cd II cation acts as a 4‐connecting node with tetrahedral geometry. The results of thermogravimetric and luminescence analyses are described in detail.
