The crystal structure of the title compound has been determined by X‐ray diffraction techniques. The structure was solved by MULTAN‐82 using the space group Aba2. The atomic parameters were refined by full‐matrix least‐squares calculations in Abam to the conventional R ‐value of 0.105, but it is impossible to interpret the results with normal space group symmetry as the title compound is an order‐disorder (OD) structure consisting of two kind of layers. The OD‐groupoid family is Ab2 1 A 1 [1/4·0].
