Assessing the Ligand Properties of NHC‐Stabilised Phosphorus(I) Cations

“…Given [103] The crystal structure of trans-[L 2 PtCl 2 ][BPh 4 ] 2 is depicted in Figure 6, and crystallisesi nP2 1 /n. The C i symmetric dicationh as PtÀPb ond lengths of 2.3181(6) ,w hicha re similar to those found for trans-[(Ph 3 P) 2 PtCl 2 ]( 2.3163 (11) ). The PtÀCl bond lengths of 2.3290(6) are, however,q uite long compared those of the PPh 3 analogue (2.2997 (11) ).…”

“…[2][3][4][5] As early as 1973, Dimroth reportedt hat silver and mercury complexes of benzimidazolylphosphamethine cyanines could be isolated as solids. [6] However,u nlike otherl ow-coordinate phosphoruscontaining compounds,s uch as phosphides, [7][8][9][10][11] phospholides, [12,13] phosphinidenes, [14][15][16][17][18][19][20][21][22] phosphinines, [23][24][25][26][27][28][29][30] phosphaalkenes, [31][32][33][34][35] isophosphindoliums [36][37][38][39] and phospheniums, [40][41][42][43][44][45] which have all seen extensive development as ligandso ver the years, the coordinationc hemistry of phosphamethine cyanine cations has remained virtually unexplored since Dimroth's seminalwork.…”

Bis(benzoxazol‐2‐yl)methanes Hounding NacNac: Varieties and Applications in Main Group Metal Coordination

“…Dilution in any other solvent causes a hydrogen shift towards the PH tautomeric form, resulting in ligand scrambling and subsequent decomposition. Despite the sensitivity of this ligand platform, it was successfully used in the coordination of different main‐group‐ (Li,Cs) and transition‐metals (Fe, Mn, Cd, Zn), exhibiting a variety of different coordination motifs based on its unique set of N, P and S donor atoms.…”

Metal complexes of a new polyimido sulfur phosphanyl ligand

“…The 31 P signal of 10 (-24.87 ppm) does not differ significantly from the signal of the lithiated compound 1 (-24.18 ppm). The First row transition metals were used to obtain the isotypical metal complexes [M{(NtBu)3SCH2PPh2}2] (M = Mn (2), Fe (3), Co (4), Ni (7), Cu (8), Zn ( 10)). The S-N, M • • • S and N-M distances as well as the N-M-N bond angles are listed in Table 3.11 to compare the structural features and to investigate the influence of the coordinated metal cation on the geometry of the ligand.…”

“…The dual N,N-coordinated iron complex is accessible by addition of [Fe{N(SiMe3)}2] to the pure ligand in Et2O. [8] The P and/or S face of the ligand are remaining vacant for a possible coordination of a second metal cation. The di(pyridyl)phosphanide ligand b is also a N,P,N-ligand.…”
