Abstract: We report a series of Pd(II)$_n$L$_{2n}$ coordination rings for whichnuclearity is controlled by the binding angle of the correspondingbis-monodentate bridging ligands. Judicious choice of theangle within a family of rather rigid ligands allowed for the firsttimeto synthesize a homoleptic five-membered Pd$_5$L$_{10}$ ring thatdoes not require any template to form. We demonstrate thatcontrol over the ring size is maintained both in the solid-,solution-, and gas-phase. Two X-ray structures of five-memberedrings from ligands with ideal angles (yielding a perfectpentagonal ring) vs. suboptimal angles (resulting in a highlydistorted structure) illustrate the importance of the correctligand geometry. A mathematical model for estimating theexpected ring size based on the ligand angle was derived andDFT computations show that ring-strain is the major factordetermining the assembly outcome.
