Non-merohedrally twinned hexamethylenetetramine–4-nitrophenol–water (1/2/1), triclinic modification
The asymmetric unit of the title cocrystal, C(6)H(12)N(4)·2C(6)H(5)NO(3)·H(2)O, contains four formula units, which are linked by O-H⋯O and O-H⋯N hydrogen bonds into chains in the crystal. The crystal studied was a non-merohedral twin, with a minor twin component of 19%.
متن کاملDesipramine hydrochloride: a non-merohedrally twinned structure
The title compound, C(18)H(23)N(2) (+)·Cl(-), is a non-merohedrally twinned salt [domains 0.9288 (3) and 0.0712 (3)] which crystallizes with four independent cation-anion pairs in the asymmetric unit. The seven-membered ring in each of the cations adopts a boat conformation, thus creating a butterfly effect within the ring system. The average value of the dihedral angle between the two aromatic...
متن کاملMIR phasing using merohedrally twinned crystals.
Merohedral twinning is a crystal-growth disorder that seriously hinders the determination of macromolecular crystal structures by isomorphous replacement. The strategies used in the structures solved so far are discussed. Several methods can be used to determine the extent of twinning, the twin fraction and to detwin the data. Accurate determination of the twin fraction by analysing heavy-atom ...
متن کاملSr5(VIVOF5)3F(H2O)3 refined from a non-merohedrally twinned crystal
The title compound, penta-strontium tris-[penta-fluorido-oxido-vanadate(IV)] fluoride trihydrate, was obtained under hydro-thermal conditions. Its crystal structure has been refined from intensity data of a non-merohedrally twinned crystal. Two domains in almost equal proportions are related by a -180° rotation along the reciprocal [101]* vector. The structure may be considered as a derivative ...
متن کاملTriclinic modification of tetrakis(triethylammonium) dihydrogenodecavanadate(V)
In the title ammonium polyoxometallate salt, (C(6)H(16)N)(4)[H(2)V(10)O(28)], the anion features O atoms engaged in μ(6)-, μ(3)- and μ(2)-bridging of adjacent V(V) atoms, confering an octa-hedral coordination at each of the twenty unique metal atoms. Two anions are linked by μ(3)- and μ(2)-bridged OH units across a center of inversion, forming a dimer which is linked to the cations by N-H⋯O hyd...
