Investigations of alkaline-earth β-diketone complexes. I. The crystal and molecular structure of bis(dimethylformamido)bis(1,3-diphenyl-1,3-propanedionato)magnesium

Properties of [Mg2(thd)4] as a Precursor for Atomic Layer Deposition of MgO Thin Films and Crystal Structures of [Mg2(thd)4] and [Mg(thd)2(EtOH)2]

“…In 1 , Mg−O distances vary from very short, 1.925(8) Å, to relatively long, 2.234(7) Å, without clear dependence on the fact that the oxygen atoms can participate in bidentate coordination and also act as a bridging atom between the metal ions. In 2 , Mg−O distances are normal with a slightly longer Mg−O(ethanol) distance, which is similar to that found in bis(dimethylformamido)bis(1,3diphenyl-1,3-propanedionato)magnesium . Also Mg−O(H 2 O) distances in the structure where water molecules lie at the apical positions the same elongation effect have been found compared to equatorial Mg−O(acac) distances …”

The crystal and molecular structure of melatonin

“…Standard deviations were estimated from counting statistics and scatter as described by Hollander, Templeton & Zalkin (1973). Zero weight was assigned to 240 independent reflections for which I<a(I), otherwise, w= 1/crZ (F).…”

Ancillary Ligand Effect on the Properties of “Mg(thd)2” and Crystal Structures of [Mg(thd)2(ethylenediamine)]2, [Mg(thd)2(tmeda)], and [Mg(thd)2(trien)]1

“…In dimeric complex 1 , three of the four thd ligands are acting as bridging ligands . In all complexes studied, the coordination polyhedron around the Mg ions is a distorted octahedron where the distances from Mg to the N atoms in cis-positions are, as is normal, ,, slightly longer than to the keto O atoms of thd (see Tables −5). The coordination planes around Mg with nitrogen atoms or hydroxylic oxygen atoms and two keto oxygen atoms are regarded as basal planes.…”
