Abstract
Diazido-dipyridine-calcium was prepared by the reaction of Ca(N3)2 with pyridine. The crystals are tetragonal, space group I\(\bar 4\)2 m (121),N=2,a=699.7 (1),c=1 450.6 (5) pm. The crystal structure was determined by single crystal X-ray diffraction, 415 independent observed Mo-Kα-counter reflexions,R=0.049. The calcium atoms are sixcoordinated to four nitrogen atoms of azide groups and to two nitrogen atoms of pyridine. The coordination polyhedra are tetragonal bipyramids which are linked together by four azide groups to form sheets of composition Ca(N3)2. The pyridine rings are directed perpendicular to the sheets.
