Alkylpyridinium lodobismuthates(III) Dịch bởi AI
Springer Science and Business Media LLC - Tập 52 - Trang 161-173 - 2021
Phản ứng của các muối iot của N-alkyl pyridinium (RPy+I−, R = Me, Et, nPr, nBu) với BiI3 đã tạo ra nhiều hợp chất alkyl pyridinium iodobismuthate(III), (RPy)y−3x[BixIy]. Một dải mức hạt nhân rộng đã được quan sát trong các cụm iodobismuthate(III) khi kết tinh từ acetone/acetonitrile: Đối với R = Me, pha chiếm ưu thế, {(MePy)[BiI4]}n, là một chuỗi của các hình lục diện BiI6 chia sẻ cạnh. Một pha kh......
Octahedral Complexes of Cobalt(III) and Nickel(II) Incorporating with Unsymmetrical NNO-Donor Hydrazone Ligand: Synthesis and Structural Aspects
Springer Science and Business Media LLC - Tập 42 - Trang 691-696 - 2012
Two new octahedral cobalt(III) and nickel(II) complexes, [CoL2]·ClO4 (1) and [NiL2]·H2O·NO3 (2) containing the potentially tridentate Schiff base like hydrazone ligand, N′-[1-(pyridin-2-yl)ethylidene]acetohydrazide (L) (1:1 condensation product of acetichydrazide and 2-acetylpyridine) were synthesized and characterized by spectral a well as thermal analysis and single crystal X-ray diffractometry.......

Molecular structure and 1H, 13C NMR assignments of 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene
Springer Science and Business Media LLC - Tập 30 - Trang 115-118 - 2000
The molecule 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb) crystallizes as a monohydrate in the monoclinic space group C2/c with a = 20.888(4), b = 13.220(2), c = 14.385(2) Å, β = 90.36(1)°. Two of three imidazole groups are on one side of the central benzene ring, and the other one is on the opposite side. The crystal packing of titmb is stabilized by O-H--N hydrogen bonding betw......
The Crystal Structure of Bis(diethylammonium) Hexachloridoplumbate(IV) Derived From Powder Diffraction Data and its Relation to Structurally Related Hexachloridometallate Salts
Springer Science and Business Media LLC - Tập 47 - Trang 173-181 - 2017
Bis(diethylammonium) hexachloridoplumbate(IV) was obtained by the reaction of PbO2 and (C2H5)2NH2Cl in hydrochloric acid solution. From the obtained crystalline powder a Rietveld refinement verified the structure of bis(diethylammonium) hexachloridoplumbate(IV) to be isotypic to the corresponding tin(IV) and platinum(IV) salts. The hexachloridoplumbate(IV) anions act as fourfold hydrogen bond acce......
