The conformational study by X-ray diffraction of 12 aroyl esters of ortho-acetyl phenols is reported. The data are supported by theoretical calculations and described in terms of co-planarity, intramolecular steric interference, and intermolecular contacts. The observed hindrance was correlated with the C=O stretching vibration values in infrared spectroscopy.

A novel metalorganic coordination polymer, namely [Co3(bpd)5.5(NCS)6(NH3)]n2H2O (1) (bpd=1,4-bis (4-pyridyl)-2,3-diaza-1,3-butadiene), has been synthesized and characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. Compound 1 presents 2D[3,4,-connected 3-nodal net with the point symbol (4268210)(4462)(8210). In addition, four identical 2D single nets is interlocked with each other in parallel, thus directly leading to the formation of a polycatenated layer (2D2D).

AbstractTwo new copper(II) complexes, {[Cu(bipmo)(npa)]}n (1) and {[Cu(bipmo)(pa)]}n (2) (bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone), were synthesized by solvothermal methods and structurally characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. The results from single-crystal X-ray diffraction data indicate that the solid state structures of 1 and 2 consist of neutral metal aromatic carboxylate layers, which are pillared by the weak interactions to generate 3D architectures. The topological structures of 1 and 2 are uninodal nets based on 4-connected nodes with the Schläfli symbol of (65·8).

AbstractThe neutral, four-fold protonated pyridine-3,5-dicarbox(3,5-dicarboxylatoanilide) (H4L) reacts with Mn(II) salts under hydrothermal conditions to yield a new complex: [Mn2(L)(H2O)2]·H2O (1), which has been characterized by single crystal X-ray diffraction, infrared spectroscopy, and elemental and thermogravimetric analyses. Complex 1 exhibits a binodal (4,8)-connected 3D framework with flu (412.612.84)(46)2 topology. The magnetic properties of 1 were investigated.
