Structures and paramagnetism of five heterometallic pentanuclear metal strings containing as many as four different metals: NiPtCo2Pd(tpda)4Cl2†
Abstract
Five heterometallic pentanuclear metal strings were prepared by stepwise synthesis from two to three and four kinds of metals aligned in one chain. In particular, NiPtCo2Pd(tpda)4Cl2 (5) possesses four different metals, and the SQUID measurement shows that Ni2+ is the only magnetically active center. Besides, the shortest Co(II)–Co(II) single bond (2.105(9) Å), so far, is reported.
