<jats:title>Abstract</jats:title><jats:p><jats:bold>Syntheses and Structure of Chiral Metallatetrahedron Complexes of the Type [Re<jats:sub>2</jats:sub>(M<jats:sup>1</jats:sup>PPh<jats:sub>3</jats:sub>)(M<jats:sup>2</jats:sup>PPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh] (M<jats:sup>1</jats:sup> = Ag, Au; M<jats:sup>2</jats:sup> = Cu, Ag, Au)</jats:bold></jats:p><jats:p>From the reaction of Li[Re<jats:sub>2</jats:sub>(μ‐H)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>(C(Ph)O)] (<jats:bold>1</jats:bold>) with Ph<jats:sub>3</jats:sub>AuC≡CPh both benzaldehyde and the trinuclear complex Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh] (<jats:bold>2a</jats:bold>) were obtained in high yield. The complex anion was isolated as its PPh<jats:sub>4</jats:sub>‐salt <jats:bold>2b</jats:bold>. The latter reacts with coinage metal complexes PPh<jats:sub>3</jats:sub>M<jats:sup>2</jats:sup>Cl [M<jats:sup>2</jats:sup> = Cu, Ag, Au] to give chiral heterometallatetrahedranes of the general formula [Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(M<jats:sup>2</jats:sup>PPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh] (M<jats:sup>2</jats:sup> = Cu <jats:bold>3a</jats:bold>, Ag <jats:bold>3b</jats:bold>, Au <jats:bold>3c</jats:bold>). The corresponding complex [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh] (<jats:bold>3d</jats:bold>) is obtained from the reaction of [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl] (<jats:bold>4</jats:bold>) with LiC≡CPh. <jats:bold>3d</jats:bold> undergoes a metathesis reaction in the presence of PPh<jats:sub>3</jats:sub>CuCl giving [Re<jats:sub>2</jats:sub>(AgPPh<jats:sub>3</jats:sub>)(CuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>C≡CPh] (<jats:bold>3e</jats:bold>) and PPh<jats:sub>3</jats:sub>AgCl. Analogous metathesis reactions are observed when <jats:bold>3c</jats:bold> is reacted with PPh<jats:sub>3</jats:sub>AgCl or PPh<jats:sub>3</jats:sub>CuCl giving <jats:bold>3a</jats:bold> or <jats:bold>3b</jats:bold>, respectively. The reaction of <jats:bold>1</jats:bold> with PPh<jats:sub>3</jats:sub>AuCl gives benzaldehyde and Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl] (<jats:bold>5a</jats:bold>) which upon reaction with PhLi forms the trinuclear complex Li[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Ph] (<jats:bold>6a</jats:bold>). Again this complex was isolated as its PPh<jats:sub>4</jats:sub>‐salt <jats:bold>6b</jats:bold>. In contrast to <jats:bold>2b</jats:bold>, <jats:bold>6b</jats:bold> reacts with one equivalent of Ph<jats:sub>3</jats:sub>PAuCl by transmetalation to give Ph<jats:sub>3</jats:sub>PAuPh and PPh<jats:sub>4</jats:sub>[Re<jats:sub>2</jats:sub>(AuPPh<jats:sub>3</jats:sub>)(μ‐PCy<jats:sub>2</jats:sub>)(CO)<jats:sub>7</jats:sub>Cl] (<jats:bold>5b</jats:bold>). The X‐ray structures of the compounds <jats:bold>3a</jats:bold>, <jats:bold>3b</jats:bold>, <jats:bold>3e</jats:bold> and <jats:bold>4</jats:bold> are reported.</jats:p>
