Abstract

The title acesulfamate complex, [Pd(C30H22FO2P2)(C4H4NO4S)], contains a four-coordinate Pd(II) ion with the expected, although relatively distorted, square-planar geometry where the four L—Pd—L angles range from 79.58 (8) to 102.47 (7)°. The acesulfamate ligand is N-bound to Pd [Pd—N = 2.127 (2) Å] with a dihedral angle of 76.35 (6)° relative to the square plane. Relatively long phen­yl–acesulfamate C—H⋯O and phen­yl–fluorine C—H⋯F inter­actions consolidate the crystal packing.

“…However, its pyrazole-ring/Ni-coordination-plane dihedral angle, 56.2 (1)°, falls significantly outside the range (3-28°) of those for the latter set of pyrazole complexes, in which none of the pendant-ligand arms exert meaningful steric force upon the pyrazole position. The C-F bond length for this complex, 1.355 (4) Å, is identical within experimental error to that, 1.357 (3) Å, of Pd{(3-2,6-[(C 6 H 5 ) 2 PO] 2 -C 6 H 2 -4-F}(C 4 H 4 NO 4 S), a Pd(II) acesulfamato complex containing a similar fluoro-pincer ligand (Wicker et al, 2011).…”
