Synthesis and Crystal Structure of Diaquabis(3,5-di(3-pyridyl)-1H-1,2,4-triazole)cobalt(II)Diformate

摘要

A novel complex daquabis(3,5-di(3-pyridyl)-1H-1,2,4-triazole)cobalt(II) diformate synthesized with a formula as [Co(C_(12)HgN5)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 3-1 H-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 P2_1/ n with unit cell parameters: a = 7.29917 (11) A,b = 11.45053 (16) A, c= 16.1982 (2) A, α = 90°, β = 95.8367 (14), γ = 90°,V= 1346.82 (3)A~3, Z = 2, M_r = 631.48, D_c = 1.557 g/cm~3, μ = 0.70 mm~(-1), F_((000)) = 650, R = 0.0288, wR (F~2) = 0.0729 for 2519 reflections with I > 2σ(I).
