In page Beryllium:

"

Beryllium has generally a rather poor affinity for ammine ligands.[3][6] Ligands such as EDTA behave as dicarboxylic acids.[citation needed] There are many early reports of complexes with amino acids, but unfortunately they are not reliable as the concomitant hydrolysis reactions were not understood at the time of publication. Values for log β of ca. 6 to 7 have been reported. The degree of formation is small because of competition with hydrolysis reactions.[3][6]
