In the title compound, [Cu(C(2)H(3)O(2))(2)(C(5)H(8)N(2))(2)], the Cu(II) atom has a distorted tetra-gonal-bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu-O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated in cis positions with respect to each other. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming a one-dimensional chain.
在标题化合物[Cu(C₂H₃O₂)₂(C₅H₈N₂)₂]中,Cu(II)原子具有扭曲的四方双锥几何构型,赤道平面由属于两个3,5-二甲基-1H-吡唑配体的两个N原子和来自两个乙酸根阴离子的两个O原子形成。乙酸根基团的第二个O原子提供拉长的Cu - O轴向接触,使得乙酸根似乎以假螯合方式配位。吡唑配体彼此处于顺式位置。在晶体结构中,分子通过分子间N - H⋯O氢键相连,形成一维链。
