چکیده
The title compound, [Ni(C11H16O2PS2)2], is a neutral four-coordinate mononuclear complex with a square-planar geometry. The complex lies on an inversion center. The metal atom is surrounded by two chelating isobidentate O-propan-2-yl (4-eth-oxy-phen-yl)dithio-phospho-nate ligands in a trans configuration binding through the S-donor atoms. The Ni-S bond lengths are 2.2328 (5) and 2.2369 (5) Å, an insignificant difference to be considered anisobidentate. The Ni⋯P separation is 2.8224 (5) Å and the S-P bond lengths are 2.0035 (7) and 2.0053 (7) Å. The S-Ni-S (chelating) and S-Ni-S (trans) bond angles are 88.321 (18) and 180°. The Ni-S-P bond angles are 83.26 (2) and 83.33 (2)°, indicating a very minor distortion from ideal square-planar geometry for the Ni atom. The P atom, however, is distorted quite significantly from an ideal tetra-hedral geometry, as reflected by the S-P-S and O-P-C bond angles of 101.93 (3) and 100.70 (7)°, respectively.
