Coordination chemistry of elemental phosphorus

Emerging Yttrium Phosphides with Tetrahedron Phosphorus and Superconductivity under High Pressures

“…[30] Meanwhile, transition metal phosphides have further boosted broad research interests due to their diversities of compositions and structures that lead to exceptional properties. [31,32] For example, P-rich 3d TMP 4 (TM = V, Cr, Mn, and Fe) have multiple structures comprising buckled phosphorus layers with P 10 rings and distinct transition-metal layers, and rich electron properties: metallic VP 4 , semiconducting CrP 4 , MnP 4 , and FeP 4 structures with varying band gaps. [33] The recent synthetic Ni 2 P 5 can be regarded as NbP 2 with infinite zigzag phosphorus chain insertion and exhibits superconductivity of 2.6 K. [34] It is noticeable that A series of molybdenum phosphides with various phosphorus-based units containing isolated P 3À ions, molecular-like P 2 , phosphorus chains, and buckled P layers have been obtained.…”

From a nanoparticular solid-state material to molecular organo-f-element-polyarsenides

“…[2][3][4] For group 15 Zintl ions, the research on molecular coordination compounds is heavily focused on phosphorus and transition metals or main group elements. [5][6][7][8] This can be ascribed to the availability of the molecular and soluble phosphorus allotrope P 4 (white phosphorus), which allows the synthesis of oen unpredictable and diverse phosphorus-containing compounds. 9 Examples for the activation of P 4 are the formation of P 4 2À and other rings such as P 5 À and P 6 .…”

“…9 Examples for the activation of P 4 are the formation of P 4 2À and other rings such as P 5 À and P 6 . [5][6][7]10 Also the opening of one edge of the P 4 tetrahedron to form buttery-type structures is known. [11][12][13][14][15] While most of these reactions were reported with main group and transition metals, f-elements were less investigated and focused more on the lighter homologue nitrogen.…”

Haptotropism in a Nickel Complex with a Neutral, π‐Bridging cyclo‐P4 Ligand Analogous to Cyclobutadiene

“…The phosphorus ring in B can σ-donate up to four lone pairs to additional metals, generating multinuclear complexes. [1] By analogy to cyclobutadiene, the P 4 ligand in B is considered to be dianionic, and this view is supported by Mössbauer measurements [11] and computational studies. [13,14] cyclo-P 4 2À has been described as antiaromatic as a free ligand, [16] lone pair aromatic in alkali metal salts, [17] and aromatic in transition metal complexes.…”

“…Transition metal complexes incorporating P x ligands have been extensively investigated due to their appealing structural variety and intriguing bonding. [1] White phosphorus is the entryway to the production of most phosphorus compounds, [2] and more recently the interest toward P x metal complexes has expanded to include the metalmediated activation and further transformation of this molecule. [3] Complexes incorporating P 4 ligands are of particular interest because they are hypothesized to constitute the first stage in the activation of P 4 .…”
