The structural properties of copper complexes with (2-hydroxyphenyl)di-p- tolylphosphane oxide (CuL12) and 3-(2-hydroxyphenyl)-3,4- dihydro-2H-benzo[f][1,5,3]dioxaphosphepine 3-oxide (CuL22) are studied in detail. The o-phosphorylated phenols demonstrate both bridging and chelating behaviour, and the main reaction product is a coordination polymer containing dimeric Cu2O8 fragments. The structural peculiarities of the o-phosphorylated phenols were revealed by single-crystal X-ray diffraction. The copper complexes are studied by single-crystal and powder X-ray diffraction, and IR, Raman and X-ray photoelectron spectroscopy (XPS). The applicability of XPS spectroscopy to structural studies of coordination compounds with complex organic ligands is demonstrated with CuL1 2 and CuL22. The results of ab initio structure solution and Rietveld refinement of the CuL22 structure from powder data are augmented by PW-PBE-D calculations. The formation of copper complexes with aromatic o-phosphorylated phenolates with both chelating and bridging configurations was demonstrated by single-crystal and powder X-ray diffraction. Photoelectron spectroscopy was utilized to reveal the coordination polyhedra around the copper ions in an amorphous copper complex. Copyright
