Synthesis of homo and hetero metal-phosphonate frameworks from bi-functional aminomethylphosphonic acid

Synthesis, structural characterization and computational studies of catena-poly[chlorido[μ3-(pyridin-1-ium-3-yl)phosphonato-κ3 O:O′:O′′]zinc(II)]

“…It revealed that the compound crystallizes in the monoclinic C2/c space group. The bond lengths and angles within the [ZnO 3 Cl] tetrahedron are in agreement with those reported for other chloride-containing zinc(II) phosphonates (Fry et al, 2008;Liu et al, 2008;Samanamu et al, 2008). The Zn II ion is four-coordinated with a distorted tetrahedral geometry.…”

“…The bond angles around the Zn II ion range from 103.54 (6) to 118.03 (7) . The bond lengths and angles within the [ZnO 3 Cl] tetrahedron are in agreement with those reported for other chloride-containing zinc(II) phosphonates (Fry et al, 2008;Liu et al, 2008;Samanamu et al, 2008).…”

A hydrophilic heterogeneous cobalt catalyst for fluoride-free Hiyama, Suzuki, Heck and Hirao cross-coupling reactions in water

“…27 They found numerous practical applications in medicinal and polymer chemistry, 28 designing fuel cell membranes 29 and building blocks in construction of metal-organic frameworks (MOFs). 30 They were used in designing new materials with special optical properties, 31 which have been employed in solar cells. 32 In the 1980s, Hirao and coworkers described the first examples of coupling of aryl and vinyl halide with dialkylphosphites using a Pd catalyst.…”

Interaction of the Zn(ii)–cyclen complex with aminomethylphosphonic acid: original simultaneous potentiometric and 31P NMR data treatment

“…The analogous reaction between ZnCl 2 and H 2 amp upon gentle heating led to a polymeric product in which the coordination sphere was formed with three oxygen atoms from three phosphonates and one chloride anion. 33 The formation of the chelate was observed in the case of derivatives with a substituted amino group. The hydrothermal reaction of (1-phenylethyl) aminomethylphosphonic acid with ZnSO 4 Á7H 2 O and NaCl in a 1 : 1 : 0.5 molar ratio, adjusted to pH = 5.7 at 140 1C, afforded crystals in which the unit contains two independent Zn(II) ions, two phosphonate ligands, and one chloride anion.…”
