Synthesis and crystal structure of trans-bis(N,N-dibutyl-N′-naphthoylthioureato) platinum(II). First example of trans chelation of N,N-dialkyl-N′-acylthiourea ligands
Abstract
N,N-Dibutyl-N′-naphthoylthiourea (HL1) reacted with [PtCl4]2– to yield a mixture of cis-(85%) and trans-[PtL12](15%); the crystal structure of the latter has been determined and represents the first example of trans chelation of N,N-dialkyl-N′-acylthiourea ligands.
