The powder X-ray diffraction pattern of [H3CNH3]B5O6(OH)4.CH3NHCOH was recorded at
298 K on a STOE Stadi P powder diffractometer (STOE, Darmstadt,
Germany) in Debye Scherrer geometry (capillary inner diameter: 0.48mm)
by using Ge(111)-monochromated CuK\a1 radiation (154.0596 pm) and a
position-sensitive detector.Extraction of the peak positions and pattern indexing and Rietveld
refinement were carried out by using the TOPAS package (version 4.1,
Coelho Software, Brisbane, Australia, 2007). Indexing was performed
using the SVD method. Structure solution was done with parallel
tempering by using the program FOX (version 1.9.8, V. Favre-Nicolin,
J. Rohlicek, M. Husak, Grenoble, 2011).The molecules chosen reflect the prior knowledge due to NMR
experiments. Rietveld refinement of the final structure model was
realized by applying the fundamental parameter approach implemented in
TOPAS (direct convolution of source emission profiles, axial
instrument contributions, and crystallite size and micro-strain
effects, using rigid bodies for the N-Methylformamide, Methylammonium and B5O6(OH)4- anion.
The used Z-Matrices for N-Methylformamide and Methylammonium were generated
using the Forcefield optimization of Avogadro (Version 1.2). The Z-Matrix
for the B5O6(OH)4- anion was extracted from the crystal structure of
Dimethylammonium Tetrahydropentaborate (ICSD-Coll.Nr.: 59897)
Moreover the 15 isotropic atomic displacement
parameters (temperature factors) for H-atoms were constrained to
1.5*Beq of the heavy atoms at which the respective H-atoms were
bound.
