Stereochemistry of the Metal-Metal Bond. The Structures of three Complexes of the Type [L2M—PR2]2The molecular structures of the complexes [(NO)2Fe—P(C6H5)2]2 (2), and [CO(NO)Co—P(C6H5)2]2 (4) were determined crystallographically. Together with literature data they allow the discussion of the metal-metal bonding in two series of complexes. In the series [L2M P(C6H5)2]2 with L2M=(NO)2Fe, CO(NO)2Co, (CO)2Ni (1,4,5) the metal-metal-bond lengths are controlled by the electronic influence of the ligands L. In the series [(NO)2Fe—PR2]2 with R=C6H5, CH3, CF3 (1,2,3) the variation of the phosphorus substituents generates only minor changes of the molecular framework.
Notes:
Die Molekülstrukturen der Komplexe [(NO)2Fe—P(C6H5)2]2 (1), [(NO) 2Fe—P(CH3)2]2 (2) und [CO(NO)Co—P(C6H5)2]2 (4) wurden kristallographisch bestimmt. Sie erlauben zusammen mit Literaturangaben die Diskussion der Metall-Metall-Bindung in zwei Komplexreihen. In der Reihe [L2M—P(C6H5)2]2 mit L2M=(NO) 2Fe, CO(NO)Co, (CO) 2Ni (1,4,5) steuert der elektronische Einfluß der Liganden L die Metall-Metall-Bindungslängen. In der Reihe [NO) 2Fe—PR2]2mit R=C6 H5, CH3, CF3 (1,2,3) bewirkt die Variation der Phosphorsubstituenten R nur unwesentliche Veränderungen des Molekülgerüstes.
