Abstract

A heterometallic and paramagnetic one-dimensional aligned chain in −Rh(+2)−Rh(+2)− Pt(+2)−Ni(+2)−Pt(+2)− with direct metal−metal bonds was obtained via HOMO–LUMO interactions at the σ* (dz²) orbital between [Rh₂(O₂CCH₃)₄] and [Pt₂Ni(piam)₄(NH₃)₄] (piam=pivalamidate). The one-dimensional chains had straight backbones attributed to face-to-face stacking of each complex, and the Ni atoms were separated by approximately 13 Å from four different metals. Each Ni atom had two unpaired electrons in the d-orbitals, which strongly exchanged with J=−37.9 cm⁻¹ through the diamagnetic −Pt−Rh−Rh−Pt− bonds.
