Cycloenantiomeric (Ligand)Transition Metal π-Complexes of Organosubstituted 2,5-Dihydro-1,2,5-azasilaborole Compounds - Characterization in the Solid StateSix π-complexes of the heterocycles [4a: R1R2R3 = CH3; 5a: R1 = C6H5, R2R3 = CH3; 7d: R1 = H, R2 = C6H5, R3 = CH3; 3a: R1 = yl, R2R3 = CH3; 4b: R1R2 = CH3, R3 = C(CH3)=CH2] with the (ligand)transition metal fragments (OC)3Cr, C5H5Co, C2H4(Cl)Ir, C2H4Rh and Ni are characterized by X-ray structure analyses: (OC)3Cr-η6-5a (2 rotamers) and the η4-cycloRS-enantiomers cycloS-C5H5Co-η4-5a-η6-Cr(CO)3; cycloS-C5H5Co-η4-7d; cycloR-C2H4(Cl)Ir-η4-4a, meso-(C2H4Rh-η1η4-3a)2 und meso-(Ni-η3η4-4bb′)2.
