trans-Bis(diethanolamine)bis(isothio-cyanato)nickel(II)

In the neutral title complex, trans-bis(2,2'-iminodiethanol-N,O)bis(isothio cyanato)nickel(II), [Ni(NCS)(2)(C4H11NO2)(2)], the isothiocyanate ions and the diethanolamine molecules act as monodentate and bidentate ligands, resp ectively. The Ni-II ion exhibits a distorted octahedral configuration with crystallographically imposed inversion symmetry and N-NCS- Ni-N-amine and N -NCS -Ni-O-amine bond angles of 88.78 (10) and 89.44 (10)degrees, respectiv ely. The Ni-N bond distances are in the range 2.069 (3)-2.096 (2) Angstrom. The molecules are linked by hydrogen bonds to form a three-dimensional inf inite lattice.
