Abstract

2+ is well documented [2]. In both molecules, the uranium ion sits at the wider entrance of the conical receptor with one U-Cl vector placed inside the cavitand. In each case, the linear PO=U=OP fragment is parallel to the plane defined by the eight oxygen atoms of the resorcinarene skeleton. All uranium metal ions lie in an octahedral environment with trans disposed phosphoryl oxygen atoms. The U···OP distances (2.312(5) Å and 2.322(5) Å in the U VI com-Z. Kristallogr.
