Full spectroscopic data for both compounds are given. A single crystal X-ray structure determination of the phenyl derivative reveals an intricate network of both intra- and intermolecular hydrogen bonds involving the C=O and both NH functionalities in all ureido groups.en540 Chemie und zugeordnete WissenschaftenTetrapodal Pentadentate LigandUreaChelatesHydrogen BondingArticle1865-7117
