Lithium-transition metal (T)-pnictides ( Pn =P, As, Sb, Bi) are an interesting class of materials with greatly differing crystal structures. The transition metal and pnictide atoms build up covalently bonded networks that leave cavities or channels for the lithium atoms. Depending on the bonding of lithium to the polyanionic network, one observes mobility of the lithium atoms. The crystal chemistry, chemical bonding, 7 Li solid-state NMR, and the electrochemical behavior of the pnictides are reviewed. The structural chemistry is compared with related tetrelides.

Metal-organophosphine complexes are very important candidates in homogeneous and heterogeneous catalysis. Many of the organophosphorus derivatives find applications in nanoscale material synthesis as important precursors. Phosphine complexes containing a variety of substituents exhibit tunable optical properties, which can be successfully applied in conjugation with nanoscale materials in solar-cell applications, photovoltaics, and the development of novel nanomaterials. In view of the emerging importance and potential applications of organophosphorus compounds, this review details the fundamental structural, synthetic, and spectroscopic characterization of organophosphines and their corresponding metal complexes. A special emphasis has been given to 31 P{ 1 H} and 1 H nuclear magnetic resonance (NMR) spectroscopic analysis.
