In the title compound, [Mn(C(10)H(5)O(4))(2)(H(2)O)(2)], the Mn(II) atom lies on a crystallographic inversion center and is six-coordinated by two O atoms from water mol-ecules in the axial positions and four O atoms from two deprotonated coumarin-3-carb-oxy-lic acid ligands in the equatorial plane. The overall coordination geometry is slightly distorted octa-hedral. The Mn-O bond distances vary between 2.0931 (12) and 2.2315 (13) Å. O-H⋯O hydrogen bonds between the H atoms of coordinated water mol-ecules and the O atoms of the carboxyl-ate groups link the complex mol-ecules into two-dimensional layers parallel to the ab plane.
在标题化合物[Mn(C₁₀H₅O₄)₂(H₂O)₂]中，Mn(II)原子位于一个晶体学反演中心上，由轴向位置的两个水分子中的O原子和赤道平面上两个去质子化的香豆素-3-羧酸配体中的四个O原子进行六配位。整体配位几何形状为略微扭曲的八面体。Mn - O键长在2.0931 (12)和2.2315 (13) Å之间变化。配位水分子的H原子与羧酸根基团的O原子之间的O - H⋯O氢键将配合物分子连接成平行于ab平面的二维层。
