The N‐acyl thiourea complexes bis[N,N‐diethyl‐N′‐(p‐nitrobenzoyl)‐thioureato]copper(II) (1a,1b) and bis(N,N‐diphenyl‐N′‐benzoylthioureato)copper(II) (2a,2b) crystallize in each case in two modifications. X‐ray structural analysis shows that 1a and 1b are cis‐trans isomers. This is very unusual for N...
