Reactions of 1 H-pyrrolo [2,3-b] pyridine (H L) with [ R h(diolefin),] [CIO,] or [ Rh,Cl,(diolefin),] compounds give mononuclear [Rh(diolefin) (HL),] [CIO,] or [RhCl(diolefin)(HL)] complexes respectively. The latter react with KOH to form binuclear [ Rh,(p-L),(diolefin),] complexes. Carbonylation reactions of the above compounds afford [Rh(CO),(HL),] [CIO,], [RhCI(CO),( HL)], or [ Rh,(p-L),(CO),]. Some related iridium( I) complexes are also reported. Redistribution reactions take place between [Rh,(p-L),(diolefin),] and [Rh,(p-L),(CO),] yielding [(diolefin)Rh(p-L),-Rh( CO),] complexes. The tetranuclear complex [ Rh,(p-CI),(p-L)?(p-CO),( CO),( nbd),] has been isolated by several routes starting from the above mono-or bi-nuclear neutral rhodium complexes. The structures of the complexes [Rh,(p-L),(nbd),] and [Rh,(p-CI),(p-L),(p-CO),-(CO),(nbd),] (nbd = norborna-2,5-diene) have been determined by X-ray methods. The former crystallizes in the monoclinic space group C2/c with a = 16.272(4), b = 7.932(2), c = 19.1 98(5) A, p = 11 2.07(2)", and Z = 4. Crystals of the latter are monoclinic, space group P2Jn with Z = 2 and a unit cell of dimensions a = 1 1.091 (3), b = 16.61 5(6), c = 8.531 (4) A, and p = 91.63( 3)". Both structures were solved by Patterson and Fourier methods and refined by fullmatrix least squares to R values of 0.072 and 0.041 respectively. The structure of the binuclear complex consists of two Rh atoms bridged by two anions L co-ordinated through the two N atoms. Each Rh atom interacts also with the olefinic bonds of a nbd molecule. The ligand L is disordered and distributed in two positions. The structure of the tetranuclear complex consists of two binuclear units joined together through a double chlorine bridge, forming a planar Rh,CI, ring. In each binuclear unit a bidentate anion L and a carbonyl group bridge the two R h atoms, which are directly bonded [Rh-Rh 2.686(2) A].
