title: catena-Poly[sodium(I)-μ-tetra-butoxy-borato].
abstract: The title compound, [Na(C(16)H(36)BO(4))](n), has a fourfold axis passing through the Na and B atoms which both are bound by four O atoms. The tetra-butoxy-borate anion provides the bridging to form one-dimensional polymers running along [001], just like those found for the tetra-ethoxy-borate structure. The two but-oxy 'tail' atoms are disordered over two conformations in a 0.887 (9):0.113 (9) ratio.
