“…The iron complex 3 crystallizes in the Table 3. Bond lengths and angles of acrylamide metal(II) perchlorate and acrylamide metal (II) tetrafluoroborate complexes 1-5 are summarized in Table 4 and compared with the structural parameters of free acrylamide [10]. In all cases, the CO bonds, the CN bonds and the vinyl CϭC bonds are longer and the central CϪC bond is shorter in the coordinated ligands than the corresponding bond lengths in free acrylamide.…”

Acrylamide complexes of metal perchlorates and tetrafluoroborates, [M(OC(NH 2 )CHϭCH 2 ) 6 ][X] 2 (M ϭ Fe, Co, Ni, Zn; X ϭ ClO 4 , BF 4 ), have been prepared and characterized using single crystal X-ray diffraction, IR spectroscopy and elemental analyses. The complexes contain metal(II) cations surrounded by an octahedral array of acrylamide ligands accompanied by the anions. The tetrafluoroborate or perchlorate counter anions do not coordinate to the metal atoms or take part in strong secondary interactions

“…At ambient conditions, acrylamide (C 3 H 5 NO) exists in the monoclinic structure with space group P2 1 /c with four formula units per unit cell, and the lattice constants are a = 8.408Å, b = 5.792Å, c = 9.777Å and b = 118 0 34'. [29] Figure 1 gives the crystal structure of acrylamide. While molecular state of acrylamide is found mainly as trans .922Å] hydrogen bonds connect two nearest dimers.…”

Acrylamide (C3H5NO), a hydrogen‐bonded amide, is an important compound from the point of view of basic and material research. It can be used as a model system for studying hydrogen bonding interactions in amides under pressure. As it is a monomer of polyacrylamide, an important polymer, high pressure investigation of polymerization in this material is also of interest. Our in‐situ high pressure Raman spectroscopic investigations of acrylamide carried out up to 17 GPa under quasi‐hydrostatic conditions indicate possible structural variations through the reconstruction of the N‐H‐‐‐O hydrogen bonds at pressures above 2.6 GPa. Emergence of several new spectral features at higher pressures indicate onset of polymerization. The characteristic polymer band becomes discernible at ~17 GPa. The increase in the relative intensity of the polymer peaks with respect to the monomer peaks on release to ambient conditions suggests that higher fraction of polymer is obtained on decompression.

“…1.308 ( 116.0 (2) where CuϪO bond lengths were found in the range between 1.952 Å Ϫ1.958 Å . The molecular structure of a free acrylamide without the coordinates of hydrogen atoms, which is a planar to a good approximation, is available in the literature [20] for comparison with coordinated acrylamide. The bond lengths Cϭ O (1.190 Å ), CϪN (1.272 Å ) and CϪC (1.760 Å ) which are reported for a syn uncoordinated acrylamide molecule, are either significantly shorter or longer than the usual bond lengths of 1.24 Å , 1.34 Å and 1.53 Å for CϭO, CϪN, and CϪC, respectively, in the structures of amides and peptides.…”
