✦ Synopsis

Cu 2 (OH) 3 (CH 3 COO) • H 2 O can be prepared by slow titration of 0.1 M copper acetate solution with NaOH 0.1 M to a OH ؊ /Cu 2؉ ratio of 1 or by heating at 50(T(75°C copper acetate solutions with concentrations in the range 0.01 M4 [Cu 2؉ ] T 40.18 M. This species has been characterized by ab initio XRPD structure determination, magnetic susceptibility measurements, and spectroscopic (XPS-XAES, FTIR) and thermal analyses. Crystals of Cu 2 (OH) 3 (CH 3 COO) • H 2 O are monoclinic, P2 1 /m, a‫,)5(5206.5؍‬ b‫,)6(0211.6؍‬ c‫)3(747.81؍‬A > and ‫,°)9(210.19؍‬ Z‫.4؍‬ Cu 2 (OH) 3 (CH 3 COO) • H 2 O is a structural analogue of the layered mineral botallackite; however, hydrogen bonded water molecules, which can be easily and reversibly removed by moderate heating, are intercalated between Cu 2 (OH) 3 (CH 3 COO) sheets.
