The Crystal-Structure of Silver(I) (2-Carbamoylphenoxy)Acetate

The crystal structure of anhydrous silver(i) (2-carbamoylphenoxy)acetate has been determined by X-ray diffraction and refined to a residual of 0.041 for 1532 observed reflections. The complex forms crystals with space group C 2/c and Z 4 in a unit cell of dimensions a 20.789(6), b 5.202(1) c 17.318(6) A, s 105.89(2)°. The structure is based on a centrosymmetric bis-carboxylate bridged dimer [Ag-O 2.228(3), 2-266(3) A, O-Ag-O 155.8(1)° Ag…Ag 3-001(1) A] which is extended into an infinite zigzag polymer through the axial positions via the carbamoyl oxygens of adjacent ligands [Ag-O 2.494(3) A]. Symmetrical long-range interactions of phenyl-carbon to silver are also found in the structure [Ag-C 3.094, 3.078(4) A].
