✦ Synopsis

overall alternating arrangement of ligands (R,R,S,S), along the c-crystal axis results[41. Thus, mixing the pure quasienantiomers (1s)-1 and (1R)-3 produces the quasiracemate as a highly ordered columnar structure with a onedimensional (Rh,Rh,Ir,Ir)chain of central atoms. The Rh-Rh, Ir-IF, and Rh-Ir distances are 3.36, 3.36, and 3.43 (k0.02) A, respectively. In the quasiracemate the metal chain is not strictly linear, since the Rh-Rh and Ir-Ir moieties are slightly displaced in the crystal lattice; the distance between the axes, which contain all Rh and Ir atoms, respectively, is 0.6 A.

The pair-wise stacking in the crystalline quasiracemate enforced by the chirality of the molecules represents a new type of one-dimensional metal chainI5I. The tailor-made synthesis of quasiracemates appears, therefore, to be a highly promising method for the construction of collective solid-state structures having alternating molecular parameters.
