The title compound, [Sn-4(CH3)(8)(C6H5N2O2)(4)O-2]center dot 6H(2)O, is a hydrated cluster containing four Sn atoms, built up by inversion symmetry around the central Sn2O2 ring. The Sn-atom coordination geometry might be regarded as very distorted SnO3C2 trigonal-bipyramidal or possibly as grossly distorted SnO3C2N octahedral. All the cluster non-H atoms, with the exception of the Sn-bonded methyl groups, lie on a mirror plane. Two of the water-molecule O atoms have m site symmetry; the other occupies a twofold rotation axis.
