Syntheses and x-ray structural characterizations of three-coordinate gold(I) and silver(I) complexes with the potentially tetradentate ligand tris(2-(diphenylphosphino)ethyl)amine (NP3): [Au2(NP3)2](BPh4)2, Au(NP3)PF6, Au(NP3)NO3, Ag(NP3)NO3, and Ag(NP3)PF6. The Au(I) compounds are luminescent

Reaction of the tetradentate «tripodlike» ligand tris(2-(diphenylphosphino)ethyl)amine (NP 3 ) with LAuX [L=PPh 3 , P(CH 2 CH 2 CN) 3 , THT; X=Cl - , NO 3 - , PF 6 - , BPh 4 - ] and AgX (X=NO 3 - ,PF 6 - ) produces the three-coordinatecomplexes [Au 2 (NP 3 ) 2 ] (BPh 4 ) 2 (dimer) (I), Au(NP 3 )PF 6 (monomer), and Au(NP 3 )NO 3 (monomer) (3), the four-coordinate Ag(NP 3 )NO 3 (monomer), and the three-coordinate complex Ag(NP 3 )PF 6 (monomer)
