Synthesis and X-ray diffraction data of dichlorodioxido (4,4-dimethoxycarbonyl-2,2′-bipyridyl) molybdenum(VI)

Abstract

The dichlorodioxido(4,4 ′ -dimethoxycarbonyl-2,2 ′ -bipyridyl)molybdenum(VI) complex was prepared from molybdenum(VI) dichloride dioxide and 4,4-dimethoxycarbonyl-2,2-bipyridyl in CH 2 Cl 2 obtaining a clear green solution. The molybdenum complex was separated by precipitation with ethyl ether. The XRPD pattern for the new compound showed that the crystalline compound belongs to the monoclinic space group P2 1 /c (No 14) with refined unit-cell parameters a = 12.104(1) Å, b = 14.933 (2) Å, c = 11.010 (2) Å and ß = 115.409°(9). The volume of the unit cell is V = 1797.6 (3) Å 3 .

Synthesis and X-ray diffraction data for dibromo-dioxo-(1,10-phenanthroline-N,N′)-molybdenum(VI) (C12H8N2MoBr2O2)

“…We have reported, over the years, the synthesis of several molybdenum complexes with bidentate chelating ligands such as bipyridyl (Páez et al, 2008(Páez et al, , 2009 and bis-pyrazolyl (Castellanos et al, 2012) ligands and studied, under homogeneous and heterogeneous conditions, their properties as oxygen atom transfer agents (Arzoumanian et al, 2010). In a previous work, we have reported the powder diffraction data of a related molybdenum complex (Camargo et al, 2014). Currently, our interest focuses on the study of the electron density effect of different bidentate ligands in oxygen atom transfer processes catalyzed by dioxo-molybdenum entity.…”
