This erratum is to correct the report of the crystal structure of strontium tetrafluoroborate (Bunič et al.
). The investigated compound was Cd(BF4
and not the reported Sr(BF4
because of experimental error. We report here the correct structure of strontium tetrafluoroborate, which appears to be isomorphous with the previously published structures of Ca(BF4
(Jordan et al.
) and Cd(BF4
(Tavčar & Žemva, 2005
). In the Sr(BF4
structure, the metal atom possesses a coordination number of eight with a square-antiprismatic coordination polyhedron. The Sr—F distances lie in the narrow range 2.490 (4)–2.538 (4) Å, compared with Ca—F distances in the range 2.330 (2)–2.401 (2) Å in Ca(BF4
and Cd—F distances in the range 2.296 (2)–2.381 (3) Å in Cd(BF4
. The Sr metal center is bonded to eight BF4
units. In turn, each anion is connected to four Sr atoms. All four F atoms in each anion act as μ2
-bridges between B and Sr atoms, resulting in similar B—F bond lengths of 1.376 (7)–1.402 (7) Å.
