[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.
