Methylsulfate Complex (Bu4N)2[Мo6I8(O3SOCH3)6]: Synthesis, Structure, Lability of Ligands, and Phosphorescence

New methylsulfate complex (Bu 4 N) 2 [Мо 6 I 8 (O 3 SOCH 3 ) 6 ] ( I ) is synthesized by the reaction of (Bu 4 N) 2 [Mo 6 I 8 (C≡C–C(O)OCH 3 ) 6 ] with dimethyl sulfate (CH 3 ) 2 SO 4 . According to the XRD data, the molybdenum atoms are coordinated by the monodentate methylsulfate ligands. In a DMS...

Description
Summary:New methylsulfate complex (Bu 4 N) 2 [Мо 6 I 8 (O 3 SOCH 3 ) 6 ] ( I ) is synthesized by the reaction of (Bu 4 N) 2 [Mo 6 I 8 (C≡C–C(O)OCH 3 ) 6 ] with dimethyl sulfate (CH 3 ) 2 SO 4 . According to the XRD data, the molybdenum atoms are coordinated by the monodentate methylsulfate ligands. In a DMSO solution, the complex undergoes solvolysis accompanied by the complete substitution of the methylsulfate ligands by the solvent molecules. A powder sample of cluster I luminesces (phosphorescence) with the emission maximum at a wavelength of 620 nm (77 K). Increasing temperature to 300 K results in the shift of the emission maximum to 650 nm and a decrease in the integral intensity by 1.6 times.
