multinuclear (31P, 13C, 1H) NMR spectra. The 12-atom metal-core architecture of this geometrically unprecedented Pd6(μ3-Pd)6(μ3-I)2(μ4-I)3 kernel of 1 of crystallographic D3 (32) site symmetry may be envisioned as a distorted hexacapped octahedral Pd(oc)6Pd(cap)6 core with its two metal-uncappedtrans octahedral Pd(oc)3 faces additionally capped by iodide μ3-I atoms. The three tetracapping μ4-I atoms are
