A binuclear manganese(II) complex: di-μ-acetato-κ⁴O:O′-bis­[bis­(1,10-phenanthroline-κ²N,N′)manganese(II)] bis­(perchlorate)

The title binuclear manganese(II) complex, [Mn₂(C₂H₃O₂)₂(C₁₂H₈N₂)₄](ClO₄)₂, has been synthesized by the reaction of manganese(II) acetate and tetra-n-butyl­ammonium manganate(VII) with 1,10-phenanthroline in a mixed solvent of acetic acid, ethanol and pyridine. In the centrosymmetric cation, the two Mn^II atoms are linked to each other by the four O atoms of two acetate ions. Each Mn^II atom adopts a six-coordinate geometry and the six coordinating atoms form a distorted octa­hedron.

The title complex, {[Mn(C₇H₃NO₄)(C₁₂H₈N₂)]·H₂O}_n, conventionally abbreviated to {[Mn(2,3-pddc)(phen)]·H₂O}_n (phen is 1,10-phenanthroline and 2,3-pddc is 2,3-pyridine­dicarboxyl­ate), has been synthesized under hydro­thermal conditions. In the complex, the Mn atom is coordinated by three O atoms of three symmetry-equivalent 2,3-pddc mol­ecules. The complex thus extends in two dimensions, resulting in the formation of a two-dimensional network structure. The complex is further assembled into a three-dimensional network by π–π stacking inter­actions involving the phen ligands.

Di-μ-acetato-κ⁴O:O′-bis­[bis­(2,2′-bipyridine-κ²N,N′)manganese(II)] bis­(perchlorate)

In the binuclear title manganese(II) complex, [Mn₂(C₂H₃O₂)₂(C₁₀H₈N₂)₄](ClO₄)₂, the Mn atoms are six-coordinate in a distorted octa­hedral coordination geometry. The two Mn atoms are bridged by two acetate groups to form a dimeric cation. The complex forms chains through π–π stacking inter­actions.
