“…Bidentate ligands such as 1,5-bis(diphenylphosphino)-pentane [152], bis[(diphenylphosphino)ethyl]sulfide [153,154] and 1,3-bis[(diphenylphosphino)methyl]benzene [155], containing five atoms between the phosphorus donors, form dimeric complexes of Type 8 (Scheme 8) when reacted with equimolar quantities of silver(I) halide. In these complexes the ligand acts as a bidentate bridging ligand, with the two phosphorus atoms coordinating to different silver atoms.…”

Silver(1) perchlorate or nitrate react readily with bis(diphenylphosphany1)-o-carborane to give the complexes [AgX((PPh2)2C2BloHlo)1 [X = C104 (l), NO3 (2)]. The perchlorate ligand is weakly bound to the silver atom and thus can be displaced by other ligands affording the three-coordi- (13), NC4H8 (14)]. The crystal structures of 11 and 12 have been established by X-ray crystallography. In both complexes the silver(1) atoms exhibit tetrahedral coordination by two phosphorus and two nitrogen or two sulfur atoms, respectively. In our studies with o-carborane derivatives as ligands we have reported on the synthesis of unusual high-coordinated gold(1) complexes with the bis(diphenylphosphany1)-o-carborane ligand[I0l. We have now extended our studies to silver(1) complexes and prepared a variety of three-and fourcoordinated derivatives where the diphosphine acts as a chelating ligand. The crystal structures of two mixed tetrahedral complexes are described here. Synthesis and Properties of the ComplexesBis(diphenylphosphany1)-o-carborane reacts with one equivalent of AgC104 in diethyl ether or with AgN03 in acetone at room temperature to give the colourless complexes 1 and 2, respectively (see Scheme 1). In these complexes the rigidity of the o-carborane moiety causes the chelating mode of thc diphosphane ligand to be preferred to the bridging mode.The reactivity of complex 1 with monodentate ligands has been studied. The reaction of 1 in dichloromethane with tertiary phosphanes leads to the three-coordinated complexes 3 or 4. These complexes can also be obtained by the reaction of [Ag(OC103)PR3] with the diphosphane ligand. Other monodentate ligands with arsenic, nitrogen, or sulfur donor atoms have been used to synthesize a variety of three-coordinated complexes of silver (1); the ligands used were tripheiiylarsane, triphenylphosphane sulfide, picolinic and quinoleic acid, whereby the latter act as monodentate ligands and cannot be deprotonated by treating the complexes with Na2C03 (Scheme 1).The use of bidentate ligands has allowed us to prepare four-coordinated derivatives, and we have again chosen ligands with various donor centres. The reaction of 1 with the bis(diphenylphosphany1)-o-carborane ligand gives the homoleptic diphosphane complex 9, also obtained by reaction of two equivalents of the ligand with AgC104; whereas with nitrogen or sulfur donor ligands such as bipy, phen, (SPPh2)CH2, or dithiocarbamates the mixed four-coordinated complexes 10-14 are obtained.

“…The electronic absorption spectrum of the title complex in THF solution at room temperature is shown in Figure 2. The intensive absorption peaks at 242 and 290 nm can be assigned to π-π* or n-π* orbital transition of the dppm ligand (intraligand IL transition), as the case found in the other dppm complexes containing other ligands, such as phen, bipy, py, 15 but quite different from that of the complex [Ag 3 (dppm) 2 I 2 ]I in MeCN with a highenergy absorption shoulder at 254 nm and a low-energy absorption tail at 335 nm.…”

“…The title complex shows an emission at 415 nm, which can be assigned to originate predominantly from ligand-to-metal charge-transfer LMCT [I − → Ag 4 ] excited state, 15 mixed with a metal-centred (ds/ dp) state. 16 While for [Ag 3 (dppm) 2 I 2 ]I complex, there is a lower energy emission at 554 nm in DMF.…”

Silver(I), whose coordination number ranging from 2 to 4, displays a wide diversity in its structural chemistry. Many silver complexes containing silver halides and neutral ligands formulated as (AgX)mLn are well known, which exist in different molecular ratios, even for the same X and L, and show rather different crystal structures. For example, there are five kinds of structures of (AgX)mLn (X = Br, L = PPh3).1 As in the case of the series of (AgX)m(dppm)n 2 (dppm = bis(diphenylphosphino)methane), they also show very interesting structures. Interest in the coordination chemistry of silver-phosphorus complexes has arisen in part from their important applications as potential antitumor, 3 free radical scavengers and catalyzer in industrial processes 4,5 since the late middle of last century. By exclusion of all traces of oxygen, a new tetranuclear silver(I) complex containing dppm ligand has been synthesized and isolated, in which the metal atoms are bridged by dppm and I − anions. The synthesis, X-ray crystal structure and photophysical properties of the complex are reported.
