Abstract
A novel complex daquabis(3,5-di(3-pyridyl)-1H-1,2,4-triazole)cobalt(II) diformate synthesized with a formula as [Co(C12H8N5)2(H2O)2(HCOO)2], was synthesized by 3,5-di(3-pyridyl)-1H-1,2,4-triazole (3-1H-bpt) and Co(HCOO)2·2H2O. In the crystal structure of the present complex, the Co(II) atom is coordinated by two N atoms from two monodentate 3-1H-bpt ligands. The crystal packing is consolidated by intermolecular O-H---N, O-H---O and N-H---O hydrogen bonds. The crystal is monoclinic, space group P21/n with unit cell parameters: a = 7.29917 (11) Å, b = 11.45053 (16) Å, c = 16.1982 (2) Å, a = 90º, b = 95.8367 (14), g = 90º, V = 1346.82 (3)Å3, Z = 2, Mr = 631.48, Dc = 1.557 g/cm3, μ = 0.70 mm-1, F(000) = 650, R = 0.0288, wR (F2) = 0.0729 for 2519 reflections with I > 2s(I).
