A　new　stable　cobalt-organic　framework,　namely　[Co-2(oba)(2)(H(2)Me(4)bPz)](n)　(1)　(H(2)oba　=　4.4＇-oxydibenzoic　acid,　H(2)Me(4)bpz　=　3.3＇,5,5＇-tetramethyl-4,4＇-bipyrazole),　has　been　synthesized　by　combining　the　mixed　H(2)oba　and　H(2)Me(4)bpz　with　Co(CH3COO)(2)center　dot　4H(2)O　under　solvothermal　conditions,　which　was　characterized　by　infrared　spectroscopy,　single-crystal　X-ray　diffraction,　powder　X-ray　diffraction,　and　thermogravimetric　analyses.　Single-crystal　X-ray　diffraction　analysis　reveals　that　1　features　a　three-dimensional　framework,　which　is　built　from　interesting　tetrahedral　cages.　The　thermal　stability　of　the　complex　has　also　been　investigated.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
