Electronic structure of the mononuclear Ag(ii) complex [Ag([18]aneS(4)O(2))](2+) ([18]aneS(4)O(2) = 1,10-dioxa-4,7,13,16-tetrathiacyclooctadecane).
The structure of [Ag([18]aneS(4)O(2))](PF(6))(2).CH(2)Cl(2) shows a highly unusual and unexpected boat conformation for the macrocycle with square-planar S(4)-coordination at the formal Ag(ii) centre and the two ether O-centres lying on the same side of the S(4) plane; the SOMO in [Ag([18]aneS(4)O(2))](2+) possesses 22.7% Ag 4d(xy) character, as determined by multi-frequency EPR spectroscopy and supported by DFT calculations.
