[1-(3-Amino­propyl)-4,7-di­thia-1-aza­cyclo­nonane-κ⁴N,N′,S,S′]­bis­(di­methyl­form­amide-κO)­nickel(II) bis­(tetra­phenyl­borate) aceto­nitrile disolvate

In the title complex, [Ni(C₃H₇NO)₂(C₉H₂₀N₂S₂)](C₂₄H₂₀B)₂·2CH₃CN, the metal centre has a distorted octahedral environment, with four coordination sites occupied by two N- and two S-donor atoms from a 3-amino­propyl pendant arm derivative of the nine-membered macrocycle 1-aza-4,7-di­thia­cyclo­nonane, and the remaining two positions by two mutually cis di­methyl­form­amide ligands.

(2,2′-Bipyrid­yl)dicarbonyl­bis(triethoxy­phosphine-κP)rhenium(I) hexa­fluoro­phosphate

In the title compound, [Re(C₁₀H₈N₂)(C₆H₁₅O₃P)₂(CO)₂]PF₆, the carbonyl ligands are mutually cis and lie trans to the N donors of the 2,2′-bipyridyl ligand, while the triethoxy­phosphine ligands are mutually trans. The Re^I centres exhibit approximate octa­hedral coordination, the major distortions from which arise from the narrow bite angle of the 2,2′-bipyridyl ligand which is expressed in the N—Re—N angles of 74.0 (3) and 74.3 (3)°. There are two cations and two anions in the asymmetric unit. The title compound is of inter­est because it has been shown to be a photocatalyst for CO₂ reduction [Ishitani, George, Ibusuki, Johnson, Koike, Nozaki, Pac, Turner & Westwell (1994). Inorg. Chem. 33, 4712–4717].
