Photochemical [2+2] cycloaddition reactions in a two-dimensional interdigitated porous crystalline framework proceed in a single-crystal-to-single-crystal manner, and one-dimensional channels show structural changes that have a significant impact on the CO(2) sorption.

in this paper, the structure of a new 16-membered macrocyclic schiff base compound n,n′-(3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzylidene)propane-1,3-diamine, c22h26n2o4 (1), derived from 1,3-propanediamine and 3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzaldehyde has been studied by single crystal x-ray diffraction, dft calculations at b3lyp/6-31g** and ft-ir spectroscopy. the titl...

The crystal structure of the title Schiff base complex is obtained by single-crystal X-ray diffraction data.The solid state structure determination reveals that the coordination geometry around the copper(II) center istetrahedrally distorted square-planar. The crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

Introduction This paper presents a few observations on single-crystal analyst*,. based upon experience with the method at the Brookhaven National Laboratory reactor during part of the summer of 1952, and a comparison of neutron and X-ray scattering.. The writer is deeply indebted to Dr. Andrew McE^yrioid and ^is group at the Brookhaven National Laboratory for furnisning the complete facilities ...

Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...
