Abstract

Reactions of [ReOCl3(PPh3)2] with the bidentate ligands 2-(2-hydroxyphenyl) benzoxazole and (2′-hydroxyphenyl)-2-thiazoline resulted in the isolation of the complexes [ReOCl2(OC6H4-2-C=NC6 H4-2-O)(PPh3)] (1) and [ReOCl2(OC6H4-2-C=NCH2 CH2S)(PPh3)] (2). Reactions of 1 with the tridentate Schiff base ligands salicylaldehyde 2-hydroxyanil (H2L1b), salicylaldehyde 2-mercaptoanil (H2L2b) and S-benzyl-2-[(2-hydroxyphenyl)methylene] dithiocarbazate (H2L3b) yielded the '3+2' rhenium(V) oxo species [ReO(OC6H4-2-C=NC6H4O) (OC6H4CH=NC6H4O)] (3), [ReO(OC6H4-2-C=NC6H4O) (OC6H4CH=NC6H4S)] (4) and [ReO(OC6H4-2-C=NC6H4O) {OC6H4CH=N-N=C(SCH2C6 H5)S}] (5). Similarly, the reactions of [ReOCl2(OC6H4-2-C=NC6 H4S)(PPh3)] (2) with H2L2b, H2L3b and 2-[(2-hydroxyphenyl) methylene]-N-phenyl-hydrazinecarbothioamide (H2L4b) were exploited to prepare [ReO(OC6H4-2-C=NC6H4S) (OC6H4CH=NC6H4O)] (6), [ReO(OC6H4C=NC6H4S) {OC6H4CH=N-N=C (SCH2C6H5)S}] (7) and [ReO(OC6H4-2-C=NC6H4S) {OC6H4CH=N-N=C(NHC6H5)}] (8), respectively.
