| Abstract: Studies on the complexes containing formate have never been stopped for a half century. In this paper, a new copper(Ⅱ) complex, [Cu2(phen)2(HCOO)2( μ-OH)2][Cu2(phen)2(H2O)2(μ-OH)2](HCOO)2·10H2O (1) (phen=1,10-phenanthroline), has been synthesized and characterized by elemental analysis, IR, and X-ray diffraction single crystal structure analysis. It belongs to triclinic system, with space group P1, a=1.151 7(3) nm, b=1.162 6(3) nm, c=1.216 0(3) nm, α=74.672(4)°, β=67.291(4)°, γ=79.029(4)°, V=1.441 4(6) nm3. The four copper(Ⅱ) ions in the complex are all 5-coordinated and exhibit a distorted square pyramidal coordination environment. The molecule are connected by intermolecular hydrogen bonds (C-H…O) interactions and π-π stacking, resulting in a three-dimensional network. CCDC: 648152. |
