title: 3-Germyl-3,3-dimethylpropionic acid derivatives.
abstract: The crystal structures of 3,3-dimethyl-3-(trichlorogermyl)propionic acid, [Ge(C5H9O2)Cl3], 3,3-dimethyl-3-(triphenylgermyl)propionic acid, [Ge(C6H5)3(C5H9O2)], and 3,3-dimethyl-3-(tri-p-tolylgermyl)propionic acid, [Ge(C7H7)3(C5H9O2)], have slightly distorted tetrahedral geometries about the Ge atoms. All the structures form dimers via strong O-H...O hydrogen bonds, resulting in eight-membered rings that can be best described in terms of graph-set notation R2(2) (8).
