Crystal structure and properties of [Cu(sac)₂(py)₃], a new example of a mononuclear complex with both N- and O-bonded saccharinate ligands

The crystal structure of the title complex has been determined by single X-ray diffraction methods and refined to an R-value of 0.0543. It crystallizes in the monoclinic P2₁/a space group with a = 21.1231(9), b = 9.4523(4), c = 16.1874(7) Å, β = 107.3706(3)° and Z = 4. The compound represents only the second known example of a simple mononuclear metal complex containing simultaneously N- and O- bonded saccharinato ligands. Its infrared spectrum and thermal behavior are also briefly discussed.

Keywords: crystal structure, saccharinato complex, IR spectrum, thermal behavior
