The title complex, [Mn(C(5)O(5))(C(12)H(8)N(2))(2)], lies across a crystallographic twofold axis which passes through the Mn atom and bisects the croconate ligand. The two 1,10-phenanthroline (phen) ligands are arranged in a propeller manner and the local mol-ecular geometry of the MnN(4)O(2) unit is severely distorted octa-hedral. This may be inter-preted as a structural perturbation of the MnN(4) square by the croconate ligand. In the crystal structure, the dipole moments of the mol-ecules are arranged alternately along the +b and -b directions. All the phen ligands are involved in π stacking inter-actions, alternately along the [110] and [10] directions. The alternate spacings between the neighbouring phen planes in the one-dimensional π stacks are 3.361 (2) and 3.526 (2) Å.
标题配合物[Mn(C₅O₅)(C₁₂H₈N₂)₂]位于一个晶体学二重轴上，该轴穿过锰原子并平分环戊二烯酮配体。两个1,10-菲咯啉（phen）配体以螺旋桨方式排列，MnN₄O₂单元的局部分子几何形状为严重扭曲的八面体。这可以解释为环戊二烯酮配体对MnN₄正方形的结构扰动。在晶体结构中，分子的偶极矩沿+b和-b方向交替排列。所有的phen配体都参与了π堆积相互作用，交替沿[110]和[10]方向。一维π堆积中相邻phen平面之间的交替间距为3.361(2)和3.526(2) Å。
