The title compound, [Mn4(O2CH)4(phen)8](ClO4)4·6H2O (1), where phen= 1,10-phenanthroline, was synthesized and its crystal structure was determined by X-ray diffraction structure analysis. The crystal is of monoclinic, space group P2/c with a= 1.928 0(16) nm, b = 1.297 0(11) nm, c =2.126 4(18) nm, V=5.242 2(8) nm3, Z=2, Mr=2 347.36,D, c=1.487 g·cm-3，μ=0.659 mm-1, F(000)=2 400, Rint=0.043 7, R=0.052 3, wR=0.118 6. The Mn atoms are octahedrally coordinated by two O atoms of two ligands and four N atoms of two 1,10-phenanthroline molecules. The carboxyl group...
