(2,2′-Bipyridyl-κ²N,N′)nitrato(triphenylphosphine-κP)silver(I)

Abstract

The title complex, [Ag(NO3)(C10H8N2)(C18H15P)], contains a bidentate bipyrid­yl ligand, a monodentate triphenyl­phosphine mol­ecule and a nitrate anion coordinated to silver. The geometry of the resulting AgN2PO coordination could be described as grossly distorted tetra­hedral or as irregular.

Unusual coordination of tetraphenylborate to silver(I): synthesis and X-ray crystal structure of the complex N,N'-bis[3-(2-nitrophenyl)allylidene]ethane-1,2 diamine(tetraphenylborato)silver(I)

“…Compound 1 crystallizes with two molecules per asymmetric unit, probably due to some small conformational differences (1A, 1B). The coordination environment around the metal ion in this complex is pseudotetrahedral, with a large angular distortion arising from the low intraligand N-Ag-N chelate angle [75.64 (13) o in 1A and 76.44 (13) [27][28][29] In the complex, the average Ag-C bond distance is 2.48 Å, which is comparable to those reported for Ag-C bond distances for coordinated polyenes. [30][31][32][33] The coordination environment around the boron atom is approximately tetrahedral, since the average of six angles involving B is 109.…”

“…Silver(I) triphenylphosphine complexes have been increasingly studied over the past decade because of their interesting structural, antimicrobial and anticancer properties (Hannon et al, 1999;Schmittel et al, 2000;Berners-Price et al, 1987). The number of ligands bound to silver(I) is greatly influenced by the chemical nature of the ligand L (Amirnasr et al, 2005;Liu et al, 2005;Amirnasr et al, 2006;Khalaji et al, 2006Khalaji et al, , 2007. In this context, we decided to examine the nature of the complex formed with a conjugated Schiff base ligand (ca 2 en) and triphenylphosphine (PPh 3 ), and (I) has been synthesized and structurally investigated.…”

Crystal Structure of Silver(I) Complex [Ag(Phca2en)(PPh3)2]ClO4, Phca2en = N,N'-Bis(.BETA.-phenylcinnamaldehyde)ethylenediimine

“…2 It is well-known that a variation in the coordination number in complexes of closed-shell d 10 metal ions can be induced by varying the ligands bound to the metal centre. [3][4][5][6][7] In continuation of our work on silver(I) complexes with bidentate Schiff base ligands, [4][5][6][7] we herein report on the structure of a monomeric Ag(I) complex, [Ag(Phca2en)(PPh3)2]ClO4 (Fig. 1).…”
