摘要：
The Cu atoms in aquabis(tert-butyl acetoacetato)-copper(II), [Cu(C8H13O13)2(H2O)], and bis(dipivaloylmethanido)copper(II), [Cu(C11H19O2)2], adopt square-pyramidal and planar conformations, respectively, with average Cu-O distances of 1.933 angstroms in the former (not including the water ligand) and 1.892 angstroms in the latter. It is interesting to note that the lability of the tert-butyl and methyl groups in both structures, which renders even the location of the terminal C atoms difficult, is reduced at T = 130 K, enabling location of all the protons in the difference Fourier map.
