Mn(Ac−)2·4H2O (0.815 mmol) was dissolved in a mixed solvent (3 ml pyridine, 12 ml acetic acid, 20 ml EtOH); fresh (C4H9)4NMnO4 (0.315 mmol) was added slowly with continuous stirring and then NaClO4 (0.565 mmol) was added. After 1 h, solid phen (2.0 mmol) was added to the reaction solution with continuous stirring. The final mixture was filtered, and the filtrate was allowed to layer with ether. After three weeks, a red pole-shaped [yellow block?] crystal of (I) was obtained. M.p. >573 K. Analysis calculated for C52H38Cl2Mn2N8O12: C 54.37, H 3.31, N 9.76%; found: C 54.23, H 3.25, N 9.71%. Selected FT–IR (KBr, cm−1): υ 3072 (m), 3000 (s), 1625 (m), 1567 (s), 1516 (s), 1494 (m), 1094 (s), 865 (w), 848 (s), 770 (w), 728 (s).
The H atoms on the ligands were positioned geometrically and refined as riding [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms, and C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms]. Please check added text.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The photosystem II oxygen-evolving complex (PSII OEC) found in the chloroplast thylakoid membranes of higher plants and algae catalyzes the splitting of water. The process is generally believed to occur on four or two manganese aggregates (Arulsamy et al., 1994). Owing to their relevance to the catalytic center of the photosystem, binuclear manganese complexes have become the subjects of intensive research. Some binuclear manganese complexes have been synthesized, such as two O atoms bridge (Tan et al., 1996; Goodwin et al., 2004), O atom and Ac− (CH3COO−) mixed bridge (Arulsamy et al., 1994; Oberhausen et al., 1993; Sheats et al., 1987; Wieghardt et al., 1985), isophthalate bridge (Tan et al., 1997) and two Ac− anions bridge binuclear manganese complexes (Oshio et al., 1993; Ishida et al., 2001; Iriller et al., 2002). We report here the title binuclear manganese(II) complex [Mn2(µ-Ac−)2(phen)4]·(ClO4)2 (phen = 1,10-phenanthroline), (I).
The molecular structure and the packing diagram of (I) in are shown in Figs. 1 and 2, respectively. The manganese complex is a centrosymmetric anion with an Mn···Mn separation of 4.588 (2) Å. The two MnII atoms are bridged by two Ac− ligends. Four N atoms of two phen ligands and two O atoms from two Ac− anions coordinate each MnII atom to form a distorted octahedron. Atoms N1, N2, O1 and N4 form the equatorial plane, the N2—Mn1—N1, N1—Mn1—O1, O1—Mn1—N4 and N4—Mn1—N2 bond angles being 72.62 (9), 162.44 (9), 102.61 (8) and 163.76 (9)°, respectively. Atoms N3 and O2 lie in the axial positions with an N3—Mn1—O2 angle of 166.39 (8)°.
