Summary

In recent years, the versatile coordinating nature and facile construction of mixed donor (O, N, S) acyl(aroyl)thiourea ligands has led to the design and synthesis of new photo-active, macrocyclic and heteroleptic complexes. Although a significant portion of the structure, synthesis and application of acylthioureas has been reviewed in the literature, this article sheds light on recent advances related to the use of acylthioureas and its derivatives as versatile ligands in the field of coordination chemistry. In particular, there has been significant progress in the preparation and study of the elusive trans-[M(L-κS,O)2] complexes prepared by photo-irradiation of corresponding cis-[M(L-κS,O)2] complexes (M = Pt(II) and Pd(II)) in solution state. A fundamental insight into the photo-active behaviour of such complexes has immense scope since their structural and physical behaviour is less explored and thus studies on the kinetics and mechanism of trans → cis isomerism is highlighted. In addition, new results obtained from spectroscopic studies of the cis/trans-[Pt(L-κS,O)2] complexes using 195Pt{1H} NMR are presented. Furthermore, the use of bipodal acylthiourea analogues as building blocks in the synthesis and design of new coordination-driven metallacycles and metallacages has seen renewed interest in the last decade. While this article does not elaborate on synthetic details, it summarizes the current collection of known acylthiourea supramolecular compounds and also includes important structural information as well as some notable properties (such as magnetism, vapochromism, bio-applications and guest–host chemistry).
