Abstract

The crystal structure of bis(3-methyl-orotato)dimanganese(II)hexahydrate, [Mn2(C6H4N2O4)2(H2O)6] has been determined by single crystal X-ray diffraction. C12H20Mn2N4O14, Mr = 554.19, triclinic, P[unk], a = 6.575(1) Å, b = 8.577(1) Å, c = 9.608(2) Å; α = 64.54(1)[unk], β = 83.01(1)[unk], γ = 89.97(1), V = 484.76 Å3, Z = 1, dc = 1.89 Mgm−3, λ(MoKα = 0.71073 Å, μ = 1.300 mm−1, F(000) = 282, T = 293 K, R = 0.037 for 2548 observed data with Fo > 3σ(Fo), 2719 unique reflections. The deprotonated 3-methyl orotato ligand coordinates to Mn(II) by the N(1) nitrogen atom and by the oxygen atom of the adjacent carboxylato group. The crystal structure consists of centrosymmetric dimeric units in which two 3-methyl-orotato ligands bridge the two metal centers by carboxylato groups. Three water molecules per metal complete the octahedral geometry.
