Dimeric lithium o-phenylenedioxydiacetate trihydrate

A novel polymeric (4-chloro-2-methylphenoxy) acetate complex of cadmium(II)

“…The polymer net is stabilized via two medium strength intramolecular hydrogen bonds [23] (Table IV) molecule are comparable to those found for the free acid [24] and its complexes [25][26][27], but standard deviations are considerably smaller. The side-chain conformation, best illustrated by the torsion angle about the oxygen atom from the phenoxy group and an adjacent acetate carbon atom (þ85.8 (3) ), is comparable to that found for the manganese complex (À80.1 ) [25], and quite different from that of the free MCPA molecule (þ173.5 ) [24]. The least-squares planes calculated through the acetate [maximum deviation À0.014(2) Å for C (9)] and the 4-chloro-2-methylphenoxy [maximum deviation À0.052(2) Å for O (1)] groups makes a dihedral angle 84.0(1) .…”

Crystal structure of the magnesium salt of the herbicide 2,4-D: pentaaqua[(2,4-dichlorophenoxy)acetato-κO]magnesium (2,4-dichlorophenoxy)acetate hemihydrate

“…Of interest have also been the structures of the metal complexes with these acids, including those with magnesium in which the monoanionic phenoxyacetate ligands (L) display a variety of coordination modes, all based on an octahedral MgO 6 metal stereochemistry. These include discrete monomeric {[MgL 2 (H 2 O) 4 ] [L = 2-(2-fluorophenoxy)acetate (Kennard et al, 1986) and L = MCPA À (Smith et al, 1981)] and [MgL(H 2 O) 5 ]ÁL [L = 2,4,5-T À (Smith et al, 1982)]} or polymeric {[MgL 2 (H 2 O) 2 ]} n [L = phenoxyacetate, (4-chlorophenoxy)acetate or (4-fluorophenoxy)acetate] (Smith et al, 1980;Smith, 2012) …”
