Crystal structure of bis(1,3-bis(diphenylphosphino)propane-κ ² P,P′)silver(I) trifluorosulfonate–methanol (1:0.5), [Ag(C₂₇H₂₆P₂)]SO₃CF₃⋅0.5CH₃OH

Abstract

Crystal structure of bis(1,3-bis (diphenylphosphino)propane-κ 2 P,P′)silver(I) trifluorosulfonate-methanol (1:0.5), [Ag(C 27 H 26 P 2 )]SO 3 CF 3 ·0.5CH 3 OH DOI 10.1515/ncrs-2016-0284 Received December 5, 2016 accepted April 11, 2017; available online May 8, 2017 Abstract C 55.50 H54AgF 3 O 3.50 P4S, triclinic, P1 (no. 2), a = 11.7859(10) Å, b = 12.8900(11) Å, c = 18.8971(17) Å, α = 109.742(2)°, β = 92.891(1)°, γ = 100.998(1)°, V = 2631.9(4) Å 3 , Z = 2, CCDC no.: 1459052The silver complex of the title crystal structure is shown in the figure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialA mixture of AgSO 3 CF 3 (0.0514 g, 0.2 mmol) and 2,5-dimercapto-1,3,4-thiadiazole (0.0150 g, 0.1 mmol) was dissolved in a mixture of 5 mL CH 3 OH and 5 mL CH 2 Cl 2 and stirred for 3 h. After 3 h, bis(1,3-bis(diphenylphosphino) propane (dppp) (0.0824 g, 0.2 mmol) was added into the mixture solvent and stirred for 3 h. Then the solvent was filtered and transferred to a beaker. Colourless crystals were obtained by slow evaporation over a week. Experimental detailsThe hydrogen atoms were generated geometrically and refined riding on the concerned atoms. The crystallization solvent was lost from the crystal and could not be resolved unambiguously. The trifluorosulfonate anion is disordered with an occupancy ratio of 0.35 : 0.65. The methanol molecule is disordered with an occupancy ratio of 0.5:0.5 near an inversion center. DiscussionIn recent years, the study on coordination chemistry of silver(I) attracts increasing interests because of their intriguing structural diversity [3] and potential application,
