[1‐(3‐Amino­propyl)‐4,7‐di­thia‐1‐aza­cyclo­nonane‐κ 4 N , N ′, S,S ′]­bis­(di­methyl­form­amide‐κ O )­nickel(II) bis­(tetra­phenyl­borate) aceto­nitrile disolvate

In the title complex, [Ni(C 3 H 7 NO) 2 (C 9 H 20 N 2 S 2 )](C 24 H 20 B) 2 ·2CH 3 CN, 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.
