The preparation, single-crystal x-ray structures, variable-temperature magnetic susceptibility, and novel EPR data are presented for two mixed-valence Mn{sup II}Mn{sup III} complexes. (Mn{sub 2}(bpmp)({mu}-OAc){sub 2})(ClO{sub 4}){sub 2}{center dot}H{sub 2}O, where bpmp{sup {minus}} is the monoanion of 2,6-bis(bis(2-pyridylmethyl)aminomethyl)-4-methylphenol, crystallizes in the monoclinic space group P2{sub 1}/n with a = 12.493 (1) {angstrom}, b = 21.583 (2) {angstrom}, c = 16.631 (2) {angstrom}, {beta} = 95.31 (1){degree}, Z = 4; R{sub F} = 0.061 and R{sub wF} = 0.085 for 4298 unique reflections (I > 3{sigma}(I)) at 297 (1) K. (Mn{sub 2}(bcmp)({mu}-OAc){sub 2})(ClO{sup {minus}}{sub 4}){sub 2}{center dot}CH{sub 2}Cl{sub 2}, where bcmp{sup {minus}} is the monoanion of 2,6-bis(1,4,67-triazacyclonon-l-ylmethyl)-4-methylphenol, crystallizes in the orthorhombic space group Pca2{sub 1} with a = 19.273 (1) {angstrom}, b = 15.155 (1) {angstrom}, c = 13.749 (3) {angstrom}, Z = 4; R{sub F} = 0.074 and R{sub wF} = 0.085 for 2324 unique reflections (I > 3{sigma}(I)) at 296 (1) K.
