The title compound, butyl­ammonium 1,3,5,7,9,11-hexa­oxa-2,4,6,8,10-penta­boraspiro­[5.5]undecane-2,4,8,10-tetraol(1−), C4H12N+·B5O6(OH)4, was synthesized under mild solvothermal conditions in the presence of 1-butyl­amine acting as a template. The structure consists of penta­borate [B5O6(OH)4] anions connected through O—H...O hydrogen bonds into a three-dimensional framework, with channels running along one direction. The [C4H12N]+ cations lie in the channels, inter­acting with the framework through N—H...O hydrogen bonds.

Experimental. The IR spectrum of (I) exhibits the characteristic bands of BO3 and BO4 groups, corresponding to the two strong bands at about 1310 cm-1 and 1016 cm-1, respectively [Yu, Z. T., Shi, Z., Jiang, Y. S., Yuan, H. M., Chen, J. S. (2002). Chem. Mater. 14, 1314–1318]. Peaks at 3362, 3185, 2962, 2883, and 1425 cm-1 are consistent with the existence of the organic amine.

Thermogravimetric analysis (TG) was performed in dry O2 atmosphere from 303 to 1273 K, with a heating rate of 10 K min-1. The TG curve of (I) showed a continuous weight loss from 503 to 913 K, corresponding to the removal of the organic amine and the dehydration of hydroxyls (Found: 39.90%, Calcd: 41.80%).

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.
