Tris(pyrazol­yl)methane and 1,8-naph­thal­imide-functionalized dialkynylgold(I) anionic complexes

D. L. Reger, M. D. Smith and R. F. Semeniuc

Abstract: The reaction of tetra­propyl­ammonium bis­(acetyl­acetonato)gold(I) with alkyne derivatives of the tris­(pyrazol­yl)methane and 1,8-naphthalimide functional groups yielded two new compounds, both bridged by the linear C[triple bond]C-Au-C[triple bond]C spacer, namely tetra­propyl­ammonium bis­{3-[2,2,2-tris­(1H-pyrazol-1-yl)eth­oxy]prop-1-yn-1-yl}aurate(I), (C16H28N)[Au(C14H13N6O)2], and tetra­propyl­ammonium {[eta]2-[mu]-3-[2,4-dioxo-3-aza­tri­cyclo­[,13]trideca-1(12),5,7,9(13),10-pentaen-3-yl]prop-1-yn-yl}bis­{3-[2,4-dioxo-3-aza­tricyclo­[,13]trideca-1(12),5,7,9(13),10-pentaen-3-yl]prop-1-yn-1-yl}digold(I) deutero­chloro­form disolvate, (C16H28N)[Au2(C15H8NO2)3]·2CDCl3. The alkyne-functionalized scorpionate ligand [Au{C[triple bond]CCH2OCH2C(pz)3}2]- features two potentially tridentate tris­(pyrazol­yl)methane donor groups oriented in a `trans' position relative to the C[triple bond]C-Au-C[triple bond]C spacer. The naphthalimide-containing compound comprises a [sigma]-bonded NI-CH2-C[triple bond]C-Au-C[triple bond]C-CH2-NI unit (NI is the naphthalimide group) [pi]-coordinated to an NI-CH2-C[triple bond]C-Au neutral fragment. The crystal packing of this compound is supported by [pi]-[pi] stacking inter­actions of the NI unit, generating a three-dimensional network containing channels accommodating the tetra­propyl­ammonium cations and deuterated chloro­form solvent mol­ecules.

Formula: (C16H28N)[Au(C14H13N6O)2] and (C12H28N)[Au2(C15H8NO2)3]·2CDCl3

Keywords: crystal structure; scorpionates; gold complexes; 1,8-naph­thal­imides.
