Under hydrothermal condition, a new three‐dimensional (3D) cobalt carboxylate metal‐organic framework Co 3 (H 2 O)L 1.5 (H 2 O) 3 (H 4 L=1,4,5,8‐naphthalenetetracarboxylic acid) ( 1 ) has been successfully synthesized. Single‐crystal X‐ray diffraction, elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X‐ray diffraction, and magnetic measurement for 1 were presented. 1 shows a new 3D framework with a 4,8‐connected {4 16 .6 12 }{4 4 .6 2 } 2 topology. Crystal data for 1 are as follows: hexagonal cell; space group P6/m , with a =12.612(5) Å, b =12.612(5) Å, c =9.978(5)(3) Å, a ;=90°, β =90°, and γ =120°; volume V= 1374.5(15) Å 3 ; and Z =2. The static magnetic behavior of 1 was conducted. The corresponding structural and magnetic parameters have been discussed in detail.
