Complexation of Polyfunctional Organic Guest Molecules by Macrocyclic Polyethers. Complexes of S-tert -Butylisothiuronium Salts with 18-Crown-6 and 1,3-Xylyl-18-crown-5
Crystalline complexes of S-tert-butylisothiuronium perchlorate ( t-BuSC(NH2),C104) and 18-crown-6 (18C6) and 1,3-xylyl-18-crown-5 (1,3X18C5) with a 1:l stoichiometry were obtained via extraction. X-ray diffraction analysis showed that in the solid state the guest molecule is coordinated via one of the two NH, groups to the crown ether. The second NH2 group is bound to the anion. 'H NMR spectros...
متن کاملX-Ray Crystal Structure of [N, N'-bis(4-Methoxysalicylidene) -2, 3-Dimethylaminopropane] Copper(II) Ethanol Solvate
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.
متن کاملThe hydrothermal synthesis and X-ray crystal structure of Ag (1)-4, 4"-bipyridine-based coordination polymer
Hydrothermal synthetic were studied for the preparation of coordination polymeric material basedon Ag (I) and 4, 4"-bipy. A polymeric compound [Ag (4, 4'-bipy)].NO3. (I), was prepared andstructurally characterized by single crystal X-ray diffraction. Compound 1(91% yield) was isolatedfrom the reaction of AgNO3 with 4, 41bipy in 2:1 molar ratio. In compound I. each silver (I) islinked to two nit...
متن کامل4′-Formylbenzo-15-crown-5
IN THE TITLE COMPOUND (SYSTEMATIC NAME 17-formyl-2,5,8,11,14-penta-oxabicyclo-[13.4.0]nona-deca-15,17,19-triene), C(15)H(20)O(6), the 15-crown-5 ring adopts a twisted conformation. The formyl group is coplanar with the benzene ring. The crystal packing is stabilized by C-H⋯O inter-actions involving the C=O group and ether O atoms as acceptors and methyl-ene CH groups as donors.
