Abstract
The solid-state structure of a dimeric ß-diketiminate magnesium(II) complex is
discussed. The compound, di- -iodido-bis[({4-amino-1,5-bis[2,6-bis(propan-2-
yl)phenyl]pent-3-en-2-ylidene}azanido- 2N,N0)magnesium(II)] toluene sesquisolvate,
[Mg2(C29H41N2)2I2] 1.5C7H8, crystallizes as two independent molecules,
each with 2/m crystallographic site symmetry, located atWyckoff sites 2c and 2d.
These have symmetry-equivalent magnesium atoms bridged by -iodide ligands
with very similar Mg—I distances. The two Mg atoms are located slightly below
( 0.5 A ° ) the least-squares plane defined by N–C—C–N atoms in the ligand
scaffold, and are approximately tetrahedrally coordinated. One and one-half
toluene solvent molecules are disordered with respect to mirror-site symmetry at
Wyckoff sites 4i and 2a, respectively. In the former case, two toluene molecules
interact in an off-center parallel stacking arrangement; the shortest C to C0 ( –
) distance of 3.72 (1) A ° was measured for this interaction.
