The syntheses and solid-state structures of K(BH<sub>2</sub>(RCN<sub>4</sub>)<sub>2</sub>)(18-crown-6) (R = H, Me, NMe<sub>2</sub>, and NiPr<sub>2</sub>) are described. Complexes where R = H and Me have B−N bonds to N<sup>1</sup> of the tetrazolyl groups and form one-dimensional polymers, whereas those with R = NMe<sub>2</sub> and NiPr<sub>2</sub> possess isomeric B−N bonds to N<sup>2</sup> of the tetrazolyl moieties and adopt chelating κ<sup>3</sup>-N,N′,H-coordination modes to the potassium ion.
