The 2D Cu II metal‐organic framework [Cu 2 (bptc)(H 2 O) 4 ] n · 4 n H 2 O ( 1 ) (H 4 bptc = biphenyl‐2,2′,4,4′‐tetracarboxylic acid) was hydrothermally synthesized and characterized by single‐crystal X‐ray diffraction and magnetic measurements. In the structure, bptc 4– serves as a twisted Π‐shaped organic building block to connect paddlewheel [Cu 2 (COO) 4 ] dinuclear units and mononuclear units through 2‐/2′‐carboxylate and 4‐/4′‐carboxylate, respectively. According to the magnetic analysis using a dimer‐plus‐monomer model, strong antiferromagnetic coupling is operative within the dinuclear unit ( J = –311 cm –1 based on H = – J S 1 S 2 ), and the compound behaves like a mononuclear molecule at low temperature.
