“…The structure of 1 is further distinguished by the coordination geometry about the Ag I cation. Though transition metal−silver complex adducts are well established, − in 1 the [Ag(MeCN) 4 ] + cation fragment assumes a square-planar geometry as opposed to the tetrahedral geometry that is normally observed for Ag I coordinated by four acetonitrile ligands. − The AgN 4 moiety is rigorously planar, as required by crystallographic symmetry, though distinctly different Ag−N bond lengths of 2.290(6) and 2.409(6) Å are observed. The [Ag(MeCN) 4 ] + cation is displaced by 0.772 Å above the Rh(1)−Rh(2) vector, and the Ag(1) metal center is located 3.4074(11) Å from Rh(1).…”

A novel one-dimensional (1D) heterometallic chain, [[Rh(2)(dfpma)(2)(MeCN)(4)](2)[Ag(MeCN)(4)]][PF(6)](5) (1), is afforded from the in situ reaction of [ClRh(cod)](2) with [Ag(MeCN)(4)][PF(6)] and dfpma (dfpma = bis(difluorophosphine)methylamine). Dichroic crystals, which are obtained from MeCN/Et(2)O solutions, crystallize in the monoclinic space group C2/m with a = 13.570(5) A, b = 20.895(9) A, c = 13.810(6) A, beta = 104.904(7) degrees, V = 3784(3) A(3), Z = 4. X-ray diffraction studies reveal an asymmetric unit comprising two Rh(I)(2) dimers and a square planar Ag(I) cation; this subunit propagates to form a 1D heterometallic chain. Compound 1 displays novel spectroscopic properties in the solid state, including temperature-dependent luminescence.
