The Adduct of Bis(O,O'-diethyl dithiophosphato)nickel(II) with 3-Aminopyridine

Abstract

The coordination compound trans-bis(3-aminopyridine)-bis(O,O'-diethyl dithiophosphato-S,S' )nickel(II), [Ni-{(C 2 H 5 O) 2 PS 2 } 2 (C 5 H 6 N 2 ) 2 ], displays distorted octahedral geometry around the central Ni atom. In the complex, two O,O'-diethyl dithiophosphate ions act as bidentate ligands with their S atoms coordinated to Ni. Each forms a four-membered chelate ring in the equatorial plane. The pyridine N atoms of the other two ligands are axially coordinated to the Ni atom. The Ni-S bond distances are 2.491(2) and 2.505 (3) A and the Ni-N bond distances are 2.103 (3) A.
