Abstract

Abstract: The synthesis and structural characterization of a series of late‐transition‐metal and divalent lanthanide complexes derived from 2‐quinolyl‐linked phosphoranosulfide CH2 ( i Pr2 P=S)(C9 H6 N‐2) are reported. Metathesis of dimeric lithium complex [(Li{Et2 O}{CH( i Pr2 P–S)(C9 H6 N‐2)})2 ] (1 ) with CoCl2 (2 equiv.) afforded a heteroleptic cobalt(II) complex [(CoCl{CH( i Pr2 P=S)2 (C9 H6 N‐2)})2 ] (2 ). Treatment of potassium complex [(K{CH( i Pr2 P–S)(C9 H6 N‐2)}) n ] (3 ) with MCl2 (M = Mn, Fe, Co; 1 equiv.) afforded homoleptic 2‐quinolyl‐linked (thiophosphorano)methanide metal(II) complexes, [M{CH( i Pr2 P–S)2 (C9 H6 N‐2)}2 ] [M = Mn (4 ), Fe (5 ), Co (6 )]. Metathesis reaction of3 with [YbI2 (thf)2 ] and [EuI2 (thf)2 ] (1 equiv.) afforded dimeric homoleptic ytterbium(II) complex [(Yb{CH( i Pr2 P–S)(C9 H6 N‐2)}2 )2 ] (7 ) and europium(II) complex [(Eu{CH( i Pr2 P–S)(C9 H6 N‐2)}2 )2 ] (8 ), respectively. The structures of2 and4 –8 have been determined by X‐ray crystallography. Furthermore, the magnetic susceptibility of compounds4 –6 have been determined by using Evan's method. Abstract : A series of homoleptic manganese(II), iron(II), cobalt(II), and divalent ytterbium and europium complexes supported by 2‐quinolyl‐linked (thiophosphorano)methane have been synthesized and characterized. The structures of all compounds have been characterized by X‐ray crystallography.
