Synthesis, crystal structure, spectroscopic and thermal characterization of (Hampy)2[Ni(pydc)2(H2O)2] · 2 H2O

“…Brought to you by | Western University Authenticated Download Date | 6/10/15 9:50 AM [10] and Co(II)-pydc complexes [8], the N Á Á Á O distances and N-H Á Á Á O bond angle are comparable to those reported complex [2.737, 2.782 A, 169.46 and 2.726 A, 156.64 ]. The coordinated water molecules link the pydc ions to the metal complex via O1--H1A Á Á ÁO3 and O1--H1B Á Á Á O4 hydrogen bonds.…”

“…, which are different with those in similar complexes [8][9][10][11][12]. The pydc ligand is almost planar and the dihedral angle between the pydc ligand and uncoordinated carboxyl group is 15.0 .…”

Aerobic homocoupling of arylboronic acids catalysed by copper terephthalate metal–organic frameworks

“…39 Elemental analysis by AAS indicated a copper loading of 2.48 mmol g −1 . [Cu( pdc) 2 ]NH 2 NMe 2 was prepared according to the previously reported procedure 40 and the prepared MOF was characterized by FT-IR and powder XRD techniques (see ESI †). The FT-IR spectra of the [Cu( pdc) 2 ]NH 2 NMe 2 exhibited the presence of a strong peak at 1652 cm −1 , which was lower than the value for CvO stretching vibration observed in free carboxylic acids 1732 cm −1 .…”

Bis(μ-pyridine-2,5-dicarboxylato)-κ3N,O2:O5;κ3O5:N,O2-bis[aqua(2,2′-bipyridine-κ2N,N′)cobalt(II)] dihydrate

“…For multi-dentate coordination modes of the pyridine-3,5dicarboxylate anion, see: Gao et al (2005). For related structures, see: Aghabozorg et al (2007); Lu et al (2006); Xu et al (2004).…”

“…2,5-PydH 2 can be easily deprotonated to get a O-donors to N-donor multidentate anion (pyd 2-), enabling the ligand coordinates to two or more metal ions in a briding mode and chelating mode (Gao et al, 2005). The complexation of metal ions using the deprotonated conjugate base of 2,5-pydH 2 as a ligand has been reported in the literature (Aghabozorg et al, 2007;Lu et al, 2006;Xu et al, 2004).…”
