Abstract
The crystal structure of the bimetallic complex between uranyl ions and the acyclic bis(hydroxymethyl)phenolic oligomer (HOCH 2 )[o-(p-Bu t C 6 H 2 OH)-o-CH 2 ] 6 OH (H 8 L) has been determined; [(UO 2 ) 2 (H 2 L)(NO 3 )][NEt 3 H] 3 ·MeOH is the first metal complex of an acyclic analogue of a calixarene structurally characterized.
