1,1'-Bis(diphenylphosphino)ferrocene complexes of platinum(II) and platinum(I). Crystal and molecular structure of [(L-L)Pt(.mu.-H)(.mu.-CO)Pt(L-L)][BF4].0.5H2O, where L-L = Fe(.eta.5-C5H4PPh2)2

The synthesis and characterisation of 1′-ethynyl-2,5-dimethylazaferrocene and derivatives

“…Microanalyses were carried out by Mr. S Boyer at SACS (Scientific Analysis and Consultancy Services) at the University of North London. 2,5-Dimethylazaferrocene [28], 1 0 -formylo-2,5-dimethylazaferrocene [16b], p-toluenesulfonylazide [29] and cis-[Pt(dppe)Cl 2 ] [30] were prepared according to literature methods. All other chemicals were purchased from the Aldrich Chemical Co.…”

Synthesis, Structure, and Electronic Properties of Monomeric and Dimeric Trispyrazolylborate Platinum(II) Hydride Complexes

“…1,2 A large group of dimeric platinum complexes with bridging hydride ligands contains the [Pt 2 H n P 4 ] m+ (n ) 1-3; m ) 1,2) core (e.g., B-D in Figure 1). These compounds are doubly hydride bridged and stabilized by monophosphine [3][4][5][6][7] or diphosphine ligands [8][9][10][11][12][13][14][15] or else they are singly hydride bridged and again stabilized by monophosphine [16][17][18][19][20] or diphosphine ligands. [21][22][23] Spencer's dimeric complexes containing the [Pt 2 H 2 (P∩P) 2 ] 2+ core (C in Figure 1), 14,15 which are yellow or red, are particularly relevant since they are direct analogues of the dicationic, N-supported dihydride-bridged dimer reported in this paper.…”

“…[21][22][23] Spencer's dimeric complexes containing the [Pt 2 H 2 (P∩P) 2 ] 2+ core (C in Figure 1), 14,15 which are yellow or red, are particularly relevant since they are direct analogues of the dicationic, N-supported dihydride-bridged dimer reported in this paper. The second large group of complexes contains mixed bridging ligands consisting of a hydride and a carbon, 11,24 sulfur, 25 phosphido, [26][27][28][29] or phosphine bridging ligand. [30][31][32][33][34][35] "Aframe" complexes are the principal subgroup in this set (E in Figure 1).…”

New Di- and Trinuclear Complexes with Pyrazolato Bridges. Crystal Structures of [{(C6F5)2Pd(μ-pz)(μ-Cl)}2Pd]2– and [(C6F5)2Pd(μ-pz)2Pd(η3-C4H7)] (pz = pyrazolate)

“…15 Hz) agree with the values found in the literature. [9,16,25] The 19 F NMR spectroscopy patterns are consistent with the presence of two nonequivalent C 6 F 5 groups, one trans to Cl and one trans to pz. As expected, the ortho F signals of complexes 2 and 4 are flanked by the satellites due to coupling to 195 Pt.…”
