Hydridoiridium(III) Complexes with Terminal and Bridging Thio‐ and Selenocyanate 1) The thio‐ and selenocyanato complexes (Ph 3 P) 2 (CO)(Cl)(H)IrX 1 (X SCN) and 2 (X SeCN) and 2 (X SeCN) have been prepared from the corresponding tetrafluoroborato‐ and trifluoromethanesulfonato‐compounds (X BF 4 , CF 3 SO 3 ). The SCN ligand in 1 is S ‐bonded. 2 was obtained as a mixture of linkage isomers. The reaction of 2 with the tetrafluoroborato‐complex (Ph 3 P) 2 (CO)(Cl)(H)IrFBF 3 gives the salt [(Ph 3 P) 2 (OC)(Cl)(H)IrSeCNIr(H)(Cl)(CO)(PPh 3 ) 2 ] + BF − 4which contains the selenocyanate‐bridged cation as a mixture of stereoisomers.
