A Mn(II) picolilato complex Mn(2-C5H4NCOO)2(H2O)2·1/2CH3CN 1 has been synthesized. Crystal of 1 is of monoclinic, space group C2/c with a = 25.6613(3), b = 8.6357(2), c = 16.8286(2) A, β = 122.835(1)β, V = 3133.47(9) A3, Mr=355.7, Dc = 1.508 g/cm3, F(000) = 1456, μ = 0.874 cm-1 and Z = 8. The final refinement gave R = 0.0362 and wR = 0.1096 for 2264 reflections (I > 2σ(I)). The Mn(II) atom possesses distorted octahedral coordination geometry and the structural parameters around the Mn ion are close to those of other Mn analogues. Extensive hydrogen bonding interactions between carboxylate and H2O were observed making one-dimensional chains of the Mn monomers.
