An incommensurate thiourea inclusion compound.
X-Ray diffraction studies reveal that the tunnel inclusion compound formed between 1-tert-butyl-4-iodobenzene and thiourea has an incommensurate relationship between the periodicities of the host and guest substructures along the tunnel axis, representing the first reported case of an incommensurate thiourea inclusion compound.

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولCrystal structure of the pyridine–diiodine (1/1) adduct
In the title adduct, C5H5N·I2, the N-I distance [2.424 (8) Å] is remarkably shorter than the sum of the van der Waals radii. The line through the I atoms forms an angle of 78.39 (16)° with the normal to the pyridine ring.
متن کاملCrystal structure of the borabenzene–2,6-lutidine adduct
In the title compound, C12H14BN, the complete mol-ecule is generated by a crystallographic twofold axis, with two C atoms, the B atom and the N atom lying on the rotation axis. The dihedral angle between the bora-benzene and pyridine rings is 81.20 (6)°. As well as dative electron donation from the N atom to the B atom [B-N = 1.5659 (18) Å], the methyl substituents on the lutidine ring shield t...
متن کاملCrystal structure of N-2-tolyl-N'-4-tolyl-thiourea.
lead and mercury poisoning in humans,1 we are currently working on the synthesis of a new series of chelating agents such as N-2-tolyl-N′-4-tolyl-thiourea (Fig. 1). In this paper, we present the crystal structure of (I). It is important to mention that there are only a few structure reports exclusively concerning substituted-thiourea derivatives, which may be due to the difficulty in preparing ...
