Pyridylimine ligands of general formula CS-{O-4-(2,5-C6H2R2)-NCH-2-Py}n, where CS is a trimethylsilyl group (n = 1, R = H, Ia or Me, Ib) or a carbosilane dendritic framework (IIa,b, n = 4; IIIa, n = 8), have been coordinated to platinum(II) and molybdenum(0) centers to give the mononuclear [(Ia,b){PtCl2}], tetranuclear [(IIb){PtCl2}4] and [(IIa){Mo(CO)3(MeCN)}4], and octanuclear [(IIIa){Mo(CO)3(MeCN)}8] complexes. The poor solubility of the polymetallic platinum compounds impedes the preparation of higher-generation dendrimers, although such a limitation is not found in the case of the more soluble molybdenum dendrimers.
A series of platinum(II) and molybdenum(0) complexes with N,N′-pyridylimine ligands of simple or dendritic carbosilane nature have been synthesized and characterized.Figure optionsDownload as PowerPoint slide
