Keywords: crystal structure ethyne gold complex; mol structure ethyne gold complex; UV ethyne gold complex; luminescence ethyne gold complex.They researched the compound: Tri(naphthalen-1-yl)phosphine( cas:3411-48-1 ).Product Details of 3411-48-1. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:3411-48-1) here.
Closely related ethynyl-Au(I) complexes were synthesized by reaction of Au(PR3)Cl with an alk. solution of the ethyne. The mol. structures of the ethynediyl-digold complexes NpPh2PAuCCAuPNpPh2·2CHCl3 (1) (Np = naphthyl), Np2PhPAuCCAuPNp2Ph·6CHCl3 (2) and Fc2PhPAuCC-AuPFc2Ph·4EtOH (3) (Fc = ferrocenyl) and the phenylethynyl-Au complex Fc2PhPAuCC-Ph (4) were determined by single-crystal x-ray diffraction measurements. Variation of the phosphines does not have a significant influence on the bonding in the central P-Au-CC unit, the Au-P and Au-C distances being in the ranges 2.274(4)-2.289(5) and 1.983(8)-2.002(6) Å, resp. Although none of the compounds have short Au…Au contacts, compounds 1 and 2 do show novel C-H…π interactions between the proton of CHCl3 and the π-electron system of the CC bond. In 1, pairs of CHCl3 mols. are located with their protons 2.4 Å from the center of the CC bond with the C-H bond directed orthogonally towards the center of the ethyne bond. In 2, two pairs of CHCl3 mols. are located around the CC bond, with 2.5 Å between the proton and the center of the triple bond, resulting in a pseudo-octahedral arrangement around CC. In addition to the C-H…π interactions, the structures of 1 and 2 also show a range of intermol. aromatic-aromatic interactions. The 1st structural determination of naphthylphosphines resulted in estimates of their steric requirements. The UV-visible spectra of CH2Cl2 solutions of the ethynediyl compounds exhibit intense absorption bands at ∼300 nm assignable to intraligand transitions. Excitation of solid sample or fluid solution of complex 1 at λ>330 nm resulted in intense long-lived luminescence. Excitation of a solution of 2 at 350 and 380 nm led to different types of photoluminescence.
