The title complex, [Mn2(O-Py3A)(DPK-CH3O)(CH3OH)]2·2ClO4·4CH3OH (C64H70Cl2-Mn4N12O22, Py3AH = N-(bis(2'-pyridyl)methyl)-2-pyridinecarboxamide, DPK = di-2-pyridyl ketone) has been synthesized and its crystal structure was determined by X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n with a = 12.667(9), b = 16.793(12), c = 17.070(13) (A), β = 100.997(13)o, V = 3565(5) (A)3, Dc = 1.537 g/cm3, Mr = 1649.98, Z = 2, μ(MoKα) = 0.851 mm-1 and F(000) = 1696. The final R and wR are 0.0639 and 0.1320, respectively for 3979 observed reflec- tions with I > 2((I). In the tetranuclear complex, each Mn(II) atom is six-coordinated and the four Mn(II) atoms are coplanar, exhibiting a parallelogram arrangement; while the deprotonated ligands are oxidized to O-Py3A2- anions and cleaved to DPK-CH3O- anions (the monoanion of mono- methylated diol of DPK) furthermore.
