Bis{μ-N-[bis(hydroxymethyl)(oxidomethyl)methyl]glycinato}bis[dimethyltin(IV)] dioxane hemisolvate
The title complex, [Sn2(CH3)4(C6H11NO5)2]·0.5C4H8O2, comprises the centrosymmetric cyclic dimeric SnIV complex and an uncoordinated, partially occupied, centrosymmetric dioxane molecule. Each SnIV atom has a distorted octahedral six-coordinate configuration formed by the tridentate tricine ligand, one bridging O atom and two methyl groups. Within the cyclic dimer, the SnSn separation is 3.6574 (4) Å. All H atoms of the NH and OH groups are involved in intermolecular hydrogen bonds with the O atoms as acceptors. There are also important weak intermolecular C—HO hydrogen bonds, which link the molecules of the dimer and dioxane into an infinite three-dimensional network.
