Niobium tetrahalide complexes with neutral diphosphine ligands.
The reactions of NbCl4 with diphosphine ligands o-C6H4(PMe2)2, Me2PCH2CH2PMe2 or Et2PCH2CH2PEt2 in a 1 : 2 molar ratio in MeCN solution produced eight-coordinate [NbCl4(diphosphine)2]. [NbBr4(diphosphine)2] (diphosphine = o-C6H4(PMe2)2 or Me2PCH2CH2PMe2) were made similarly from NbBr4. X-ray crystal structures show that [NbCl4{o-C6H4(PMe2)2}2] has a dodecahedral geometry, but the complexes with...
متن کاملLead(II) nitrate and hexafluorosilicate complexes with neutral diphosphine coordination.
Rare examples of phosphine complexes of lead(II) are reported. The reaction of Pb(NO3)2 with Me2P(CH2)2PMe2, o-C6H4(PMe2)2 or Et2P(CH2)2PEt2 (L-L) in H2O/MeCN gave white [Pb(L-L)(NO3)2], irrespective of the ratio of reagents used. The X-ray structures of [Pb{Me2P(CH2)2PMe2}(NO3)2] and [Pb{o-C6H4(PMe2)2}(NO3)2] reveal chelating diphosphines and κ(2)-NO3(-) groups occupying one hemisphere about t...
متن کاملLuminescent gold-silver complexes derived from neutral bis(perfluoroaryl)diphosphine gold(I) precursors.
Complex [Au{4-C(6)F(4)(4-C(6)BrF(4))}(tht)] reacts with diphosphines (L-L) such as bis(diphenylphosphino)methane (dppm) or 1,2-bis(diphenylphosphino)benzene (dppb) in a 2 : 1 molar ratio in dichloromethane, leading to neutral products of stoichiometry [(Au{4-C(6)F(4)(4-C(6)BrF(4))})(2)(μ-L-L)] (L-L = dppm (1), dppb (2)). In the crystal structure of complex 2 short Au···Au interactions of 2.9367...
متن کاملSilver Diphosphine Complexes as Antimitochondrial Agents
Like their Au(I) counterparts, silver complexes of the type [M(R'2P(CH2)nPR'" 2)2 exhibit potent cytotoxicity towards cancer cells in vitro, ,2 in addition, they show antifungal and modest antibacterial properties. 2 However, none of these has reached clinical trials because of extreme mitochondrial toxicity related to uncoupling of oxidative phosphorylation for the gold(I) analogues. 3 We now ...
متن کاملPhosphine and diphosphine complexes of tungsten(VI) oxide tetrafluoride
The reaction of [WOF4(MeCN)] with the diphosphines, Me2PCH2CH2PMe2 or o-C6H4(PMe2)2, in anhydrous Et2O produced high yields of [WOF4(diphosphine)], the X-ray crystal structures of which reveal seven-coordinate pentagonal bipyramidal molecules with axial O/F. In contrast, the reaction of [WOF4(MeCN)] and PMe3 forms the six-coordinate [WOF4(PMe3)]. These unusual W(VI) complexes have been characte...
