The incommensurately modulated twinned crystal structure of lazurite from the Baikal region is presented for the first time. The orthorhombic structure was solved in a pseudo cubic unit cell, a(cub) = 9.077(1) Angstrom, and in the (3 + 2)D superspace group ...
The equimolar reaction of t-BuP(NH2)2 and Et2AlH yields [t-Bu(H)P(NH)2AlEt2]2 I, a novel eight-membered heterocycle contg. an AlNP-backbone; the crystal structure of which was detd. [on SciFinder (R)] ...
We recently proposed two-dimensional coupled photonic crystal microcavity arrays as a route to achieve a slow-group velocity of light (flat band) in all crystal directions. In this letter we present the experimental demonstration of such structures with a ...
We have determined the crystal structure of YodA, an Escherichia coli protein of unknown function. YodA had been identified under conditions of cadmium stress, and we confirm that it binds metals such as cadmium and zinc. We have also found nickel bound in ...
Mycobacterium leprae protein ML2640c belongs to a large family of conserved hypothetical proteins predominantly found in mycobacteria, some of them predicted as putative S-adenosylmethionine (AdoMet)-dependent methyltransferases (MTase). As part of a Struc ...
N-Salicylideneaniline (SA), C13H11NO, belongs to the large family of aromatic Schiff bases. It is of particular importance owing to its reversible photoreactivity. SA forms two photochromic polymorphs, both with two non-coplanar benzene rings. In addition, ...
The previously proposed model postulating that the incommensurately modulated KNd(MoO4)2 structure can act as a generator of the scheelite family members is validated here by refining the crystal structure of europium molybdate, Eu2(MoO4)3. ...
Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...
The crystal structure of a strontium-imidazolium polymeric material obtained from the reaction of zwitterionic 1,3-bis(carboxymethyl)-imidazolium with SrCO3 (2:1) in water is reported. The compound crystallized in the orthorhombic space group Pcc2 with a = ...
A new cubic Ta-bronze (1) KTa1+z+(5-delta)O3 [z similar or equal to 0.107 (3)] was obtained on a cathode by molten salt electrolysis of the system K2TaOF5-K3TaO2F4-(KF + NaF + LiF)(cutectic). Black, metallic cubic crystals of (1) are formed together with t ...
