Lewis base adducts of NpCl4†
Abstract
Np(IV) Lewis base adducts were prepared by ligand substitution of NpCl4(DME)2. Using acetonitrile and pyridine, NpCl4(MeCN)4 (1) and NpCl4(pyr)4 (2) were isolated, respectively. Addition of t-butylbipyridine and triphenylphosphine oxide generated the respective Lewis base adducts, NpCl4(tBuBipy)2 (3) and NpCl4(OPPh3)2 (4). All species were fully characterized using spectroscopic and structural analyses.
