Four isostructural cobalt(II)–lanthanide(III) heterometallic metal–organic frameworks (MOFs), formulated as {[(CH 3 ) 2 NH 2 ] 3 [Co 3 Ln(tda) 3 (HCOO) 3 ] 2H 2 O 0.75dmf} n [Ln = Eu ( Co‐Eu ), Gd ( Co‐Gd ), Tb ( Co‐Tb ), and Dy ( Co‐Dy ); H 3 tda = 1 H ‐1,2,3‐triazole‐4,5‐dicarboxylic acid] have been successfully synthesized and structurally characterized in detail. In these Co‐Ln heterometallic MOFs, three neighboring Co II ions are connected by HCOO – anions to form triangular [Co 3 (HCO 2 ) 3 ] 3+ clusters. The equivalent triangular [Co 3 (HCO 2 ) 3 ] 3+ clusters are connected by six tda 3– anions to generate a 1D trigonal prismatic chain, which are further interconnected through Ln III ions to give unique 3D (6,6)‐connected nia nets with the Schläfli symbol of (4 12 6 3 ) (4 9 6 6 ). The magnetic properties of the four isostructural Co‐Ln heterometallic MOFs have also been studied.
