′-menthyloxycarbonylthioureas. Crystal and molecular structures of N,N-diethyl-N
′-(−)-(3R)-menthyloxycarbonylthiourea and cis-(S,S)-[Pt(L)Cl(DMSO)] [where HL = N-(+)-(3R)-menthyloxycarbonyl-N′-morpholinothiourea or N-benzoyl-N′,N′-diethylthiourea]
Abstract
The novel ′-(−)-(3R)-menthyloxycarbonylthiourea (HL3), N,N-diethyl-N
′-(+)-(3R)-menthyloxycarbonylthiourea (HL4), N-(−)-(3R)-menthyloxycarbonyl-N
′-morpholinothiourea (HL5) and N-(+)-(3R)-menthyloxycarbonyl-N
′-morpholinothiourea (HL6) have been prepared and characterised. The molecular structure of HL3 has been confirmed by
′-menthyloxycarbonylthiourea
′,N
′-diethylthiourea (HL1) or
