Anhydrous copper(II) octanoate

Nuclear Magnetic Resonance Spectra and 207Pb Chemical-Shift Tensors of Lead Carboxylates Relevant to Soap Formation in Oil Paintings

“…43 Differences in packing have also been noted for copper octanoate and copper decanoate. 44,45 Oleic acid is a precursor to azelaic acid in dried oils, 14 so lead oleate's NMR parameters provide important information on a potential intermediate in the reactions that may lead to soap formation. We did not measure the spin-lattice relaxation time, but from STA experiments, we know that a longer relaxation delay (20 s) is necessary to achieve a spectrum of high quality, whereas for the other lead-containing materials, a recycle delay of less than 5 s was adequate.…”

Structure and preliminary electron distribution of copper heptanoate from room-temperature X-ray data

“…The agreement between experimental and estimated c values is good when n is greater than 6. [Cu2(C28H5208)] References: (i) Bird & Lomer (1972), (ii) this study, (iii) Lomer & Perera (1974a), (iv) Lomer and Perera (1974b).…”

Synthesis and characterization of Cu(II) paddlewheel complexes possessing fluorinated carboxylate ligands

“…The hexanoate complex is comparable to 6, with a Cu-Cu distance of 2.5791 (5) Table 3 Selected bond lengths (Å ) and angles (8) (Cu-Cu: 2.575 Å´, CuÁ Á ÁCu 3.269 Å´) [29], and decanoate (Cu-Cu: 2.624 Å´, CuÁ Á ÁCu 3.365 Å´) [30]. Though other polymeric copper(II) carboxylates have been reported [14,15,24,[27][28][29][30], compound 6 appears to be the first such structure possessing a fluorinated carboxylate ligand and subsequent close C-FÁ Á ÁH-C interactions between individual polymer chains (C-FÁ Á ÁH-C interactions of 2.448, 2.823, and 3.044 Å´; Fig. 5).…”
