Abstract Among the new compounds of N-(thio)phosphorylthiómides. the copper(II) complex with N-diisopropoxyphosphorylthiohenzamide (Cul. 2) exhibits series of unusual properties which have been extcnsively investigated in the present work. The X-ray structure of CuL2 has been determined Crystals of CuL2 are monoclinic. P21/c, a = 15.610, b = 11.880, and c = 18.320 Å, β = 106.74°. Z = 4. The CuL2 complex has the cis-structure with Cu-S distances ranging from 2.238 to 2.253 Å and Cu-O distances being from 1.919 to 1.937 Å (Figure). 相似文献

The first part of this report describes the data reduction of non-merohedrally twinned crystals measured on Bruker and Agilent area-detector diffractometers. The image frames of methyl-2-aminopyrazine-3-carboxylate were processed with APEX2 to furnish a set of overlapping diffraction indices that were used for solution and refinement. CrysAlisPRO was used for processing the frames of bis(diethyldicarbamato)nickel, which exists in monoclinic and tetragonal polymorphs, and in untwinned and twinned forms. In the second part, the crystal structure of [(3-formyl-4- hydroxyphenyl)methyl]triphenylphosphanium chloride was refined through the ‘HKLF 5'(based on a combined set of diffraction indices) and PLATON(based on one set of diffraction indices) routes to give identical outcomes because the amount of overlap of the twin domains is small. For the third part, in a proof-of-concept investigation, the diffraction pattern of untwinned and twinned 4-{(E)-(4-aminophenyl)diazenyl]phenylamine was recorded simultaneously in one run; the three domains could be indexed and the crystal structure satisfactorily refined. The refinement was identical to those derived from independent measurements; the crystal structure features two independent centrosymmetric molecules, one of which is ordered and the other whole-molecule-disordered. This two-in-one run opens up the possibility that two or more crystals having different atomic compositions can be measured simultaneously if their reciprocal lattices do not overlap significantly. 相似文献

Dimethyltin dichloride-dibenzyl sulfoxide,((CH3)2SnCl2·O=S(CH2C6H5)2),crystallizes in the orthorhombic space group P212121 with a superstructure of dimensions a = 11.9290(1),b = 19.50490(1),c = 55.7390(6) ; Z = 28. The geometry of the five-coordinated tin atom in each of the seven independent adduct molecules is a square pyramid that is displaced towards a cis-trigonal bipyramid; the extent of displacement along the Berry pseudorotation pathway ranges from 20 to 45%. 相似文献

Complexing processes in MII-N-diisopropoxythiophosphorylthiobenzamide binary systems (M = Co, Ni, Cu) in metal(II) hexacyanoferrate(II) gelatin-immobilized matrices upon contact with aqueous–alkaline (pH = 12.0 ± 0.1) solutions of organic compounds have been studied. It has been shown that, in CoII and CuII, the initial act of complexing involves destruction of the CoII and CuII hexacyanoferrates(II) by OH– ions, leading to formation of the corresponding hydroxides which react with the ligand indicated. In the both systems, successive addition of two ligand molecules per M(OH)2 fragment occurs and [MB(OH)(OH2)] and [MB2] coordination compounds are formed (B–-a singly deprotonated ligand form). In the NiII-N-diisopropoxythiophosphorylthiobenzamide system, the formation of three complexes, (Ni2BOH)2[Fe(CN)6], [NiB(OH)(OH2)] and [NiB2] occurs. 相似文献

In this study, a variational approach to the settlement analysis of an axially loaded pier embedded in a multi-layered soil
profile is presented. In this method, the soil profile and the embedded pier are divided into a number of sub-layers according
to the actual number of soil layers observed in the field. The displacement shape function of each soil layer is given as
a product of an exponential equation along the pier depth and the Bessel's solution in the radial direction. The displacement
relationship among the layers can be derived through the transformation matrices. One of the major features of this method
is that the total number of pier elements is the same as that of soil sub-layers. All the field components, such as the displacement,
stress, and strain in the soil, can be calculated by closed-form solutions except that the only unknown variable is the value
β which can be determined by iteration techniques. Comparisons were made with the results of finite element analysis and the
field observation in pile-loaded tests. 相似文献
