Abstract：

The　asymmetric　unit　of　the　title　coordination　polymer,　[Co(C9H4N2O4)-　(C2H4N4)]n　or　[Co(L1)(L2)]n,　consists　of　one　crystallographically　independent　Co2+　centre,　one　L12-　ligand　and　one　L2　ligand　(L1　=　1H-benzimidazole-5,　6-　dicarboxylic　acid,　L2　=　3-amino-1,　2,　4-triazole).　The　Co2+　centre　is　coordinated　by　two　carboxylato-O　atoms　from　two　independent　L12-　ligands　and　two　nitrogen　atoms　from　L2　and　another　L1　ligand.　Thus,　the　metal　center　adopts　a　four-coordinate　mode,　forming　a　tetrahedral　geometry.　Interestingly,　through　the　combination　of　two　L12-,　two　L2　ligands　and　two　Co2+　ions,　a　basic　repeating　unit　is　constructed,　resulting　in　the　formation　of　a　one-dimensional　straight　chain　structure.　These　chains　are　further　expanded　to　the　final　threedimensional　framework　via　N-H···O　hydrogen-bonding　interactions.　　©　2021　International　Union　of　Crystallography.　All　rights　reserved.
