A dinuclear manganese(Ⅱ) complex, [Mn2(L1)2(phen)4]· (ClO4)2 (1), has been synthesized and structurally characterized (HL1=2,6-dichlorobenzoic acid, phen=1,10-phenanthroline). It crystallizes in triclinic system, space group P1- with α=1.112 3(4) nm, b=1.378 2(4) nm, c=2.085 7(3) nm, α=93.768(2)°, β=90.606(10)°, γ=95.606(3)°,V=3.174 8(15) nm3, Z=2, C62H38Cl6Mn2N8O12, Mr=1409.58, Dc=1.475 g·cm-3,μ=0.718 mm-1, F(000)=1428, R=0.064 3, wR=0.138 3. In the crystal the manganese atom is six-coordinated by two oxygen atoms from two different 2,6-dichlorobenzolate molecules and four nitrogen atoms from two 1,10-phenanthroline molecules, completing an octahedral geometry. CCDC: 692296.
