Abstract
Compounds RXHal2 (X = P, As, Sb) react with Na2[M2(CO)10] (M = Cr, Mo, W) to yield three types of products: A, [(CO)5M]2X-R containing trigonally planar coordinated X; C, [(CO)5M]3X-R containing coordinated metallacyclic ligands; B, [xxx] D, [(CO)5M]n (R)X = X (R) (n = 0, 1, 2, 3). The relation between these species, especially the one based on the valence tautomerism between A und B, is experimentally verified. Preparative, spectroscopic and X-Ray-structural results reveal a consistent picture of the relevant chemistry.Keywords
