摘要:
The crystal structure of the title compound, [ZrCl4(C4H8O)(2)](2)O or [Zr2Cl6O(C4H8O)(4)], (I), was solved at room temperature and compared with that of the earlier reported complex [ZrCl3(MeOCH2CH2OMe)(2)](2)O, (II). In both molecules, two equivalent quasi-octahedral fragments involving one axial (ax) and one equatorial (eg) ether oxygen share one bridging oxide functionality However, the point symmetry of (I) is only C-2. while that of (II) is C-2h The dihedral angle of the O-eq-Zr-Zr-i-O-eq(i) fragment of (I) [symmetry code: (i) 1-x, y, 1/2-z] is 115.3(1)degrees [180.0 degrees in (II)] and the Zr-O-Zr-i angle is 174.8(2)degrees [180.0 degrees in (II)].
