The transesterification and hydrolysis of [ η 6 - p -C 6 H 4 (CH 2 PO 3 Et 2 ) 2 ]Cr(CO) 3 afforded the organometallic bisphosphonic acid [ η 6 - p -C 6 H 4 (CH 2 PO 3 H 2 ) 2 ]Cr(CO) 3 ( 3 ) in 81% isolated yield. The bisphosphonic acid complex has been characterized by NMR and IR spectroscopies and its molecular structure determined by X-ray crystallographic analysis which represents the first structural analysis of an organotransition metal derived phosphonic acid. Compound 3 reacts with Zn(NO 3 ) 2 in aqueous methanol to give a hybrid inorganic—organometallic material in which the arene chromium tricarbonyl fragment remains intact.
