The synthesis, structure, and three-dimensional lamellar array of a series of trans-bis(2-aminotroponato-κN,κO)palladium(II) complexes bearing linear alkyl chains (1a: n = 5; 1b: n = 8; 1c: n = 14; 1d: n = 16; 1e: n = 18, where n is the number of carbon atoms in the chain) attached to trans nitrogen donor atoms are described. The trans-coordination of the ligands, the cross-shaped molecular structures, and the crystal packing of 1b and 1c have been unequivocally established from single-crystal XRD studies. Highly regulated multilayered lamellar structures are observed for 1b and 1c, where every lamellar layer in the crystallographic ab plane, formed by π-stacking interactions of metal cores and van der Waals[a]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
