32. c) The degree of distortion was calculated by using the dihedral angle method described in refs. [8a] and [8b]. All nine dihedral angles and the values for the reference geometry of the ideal square pyramid given in ref. [8a] were considered for this calculation.
33. The disorder originates from two different conformations of the envelope shaped five-membered ring Si-N3-C6-C7-N4, which cause a split position of the atom C6, so that C6A (80 % occupied) approaches N1 while C6B (20 % occupied) approaches N2. The split positions C6A and C6B lead to a similar splitting of the atoms C4 and C5 which are bonded to the common atom N3.
34. 15N NMR signals could be detected in solution.
