We present the formation of a series of chiral metallacycles and metallacages by the use of a BINOL-derived dicarboxylate as a donor that is capable of affording a variety of coordination angles between its two Lewis basic sites. Two squares, two rhomboids, two tetragonal prisms, and one hexagonal prism were successfully formed when the chiral dicarboxylate donor self-assembled with one of four ditopic Pt(II) complexes, including two bimetallic 180掳 Pt-based acceptors, a 120掳 bimetallic Pt-based acceptor, and a 90掳 mononuclear Pt-based acceptor. Their structures were well characterized by ³¹P{¹H} NMR, ESI-MS, CD, and optical rotation analyses.
