The title compound, C
6H
13N
4+·ClO
4−, crystallizes in the space group
P2
1/
n. The structure can be solved in the orthorhombic space group
Pnma, but analysis of the refinement parameters showed that the choice of the
P2
1/
n space group is the correct one. All interatomic distances can be considered as normal. Molecules are assembled by intermolecular N—H
O hydrogen bonds into a zigzag chain structure along the
b axis. In the structure, weak intermolecular C—H
N hydrogen bonds create a two-dimensional net structure in the (011) plane.

Because collected data were relatively weak, there is a large amount
of reflections with small intensities, and a part of reflections
was marked as unobserved and excluded from the data set by diffractometer
data reduction software. This affect fraction of unique
reflections observed (out to \q=25\%) which is equal to 94%.

Special details top
Experimental. Because collected data were relatively weak, there is a large amount of
reflections with small intensities, and a part of reflections was marked as
unobserved and excluded from the data set by diffractometer data reduction
software. This affect fraction of unique reflections observed (out to θ=25°)
which is equal to 94%. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |
