Figure 1 Asymmetric unit of (I) along with equivalent atoms with labelling and thermal ellipsoids at the 50% probability level. F1i-iii,v,vi,ix-atoms (sof 1/2) correspond to the second component of the disordered dianion and are depicted as small spheres surrounded with thermal ellipsoids as rims. Symmetry equivalents of the methanol molecule (disordered between 12 positions) are not depicted for clarity. Symmetry codes: (i) x, y, –z; (ii) –x + y, –x, –z; (iii) x–y, x, z; (iv) –x, –y, –z; (v) –y, x–y, –z; (vi) y, –x + y, z; (vii) –y, x–y, z; (viii) y, –x + y, –z; (ix) –x, –y, z; (x) –x + y, –x, z; (xi) x–y, x, –z; (xii) –x + y+1, y, –z + ; (xiii) –y + 1, x–y, z; (xiv) x, x–y, –z + ; (xv) –x + y+1, –x + 1, z; (xvi) –y + 1, –x + 1, –z + . |
