Self-assembly of homochiral double helix and side-by-side helix conformers of a double-stranded disilver(I)–tetra(tertiary phosphine) complex
Abstract
Optically pure (S,S)-(+)-Ph2PCH2CH2P(Ph)CH2CH2P(Ph)CH2CH2PPh2, (S,S)-1, spontaneously self-assembles into left-handed double-stranded D2-double helix and C2-side-by-side helix conformers of the disilver(I) cation; the crystal and molecular structure of Λ-(–)-[Ag2{(R,R)-1}2][PF6]2 is reported.
