title: A face-capped [Fe4L4]8+ spin crossover tetrahedral cage.
abstract: Reported here is a face-capped Fe(ii) molecular tetrahedron, [Fe(4)L(4)](BF(4))(8), . Single crystal X-ray diffraction at 153 and 293 K suggest spin crossover (SCO) and variable temperature magnetic susceptibility measurements confirm  displays thermally driven SCO behaviour in the solid state and in dilute acetone solution centred around 284-288 K.
