Novel Coordination Behavior of fac-[ReBr3(CO)3]2- with 1,3,5-Triaza-7-phosphaadamantane (PTA). Systematic Investigation on Stepwise Replacement of the Halides by PTA Ligand. Phase Transfer Studies and X-ray Crystal Structure of [NEt4][ReBr2((PTA)(CO)3], [ReBr(PTA)2(CO)3], and [Re(PTA)3(CO)3]PF6

Abstract

Starting originally from [NEt4]2[ReBr3(CO)3] (1), the three novel complexes [NEt4][ReBr2(PTA)(CO)3] (2), [ReBr(PTA)2(CO)3] (3a), and [Re(PTA)3(CO)3]PF6 (4) (PTA = 1,3,5-triaza-7-phosphaadamantane) ...
