 Title    (MePNMe)4 Mel und (MePNMe)4 2 Mel, ein Cyclotetra(A 3 .A 3 .A 3 .A 5 -) und ein Cyclotetra(A 3 .A 5 .A 3 .A 5 -phosphazan) (MePNMe)4 * Mel and (MePNMe)4 * 2 Mel, a Cyclotetra  
 Abstract    (2) with three P 111 and one P v , and (3) with two P In and P v atoms are prepared from 1 with methyl iodide. NMR spectra of 2 are compared with those of the recently prepared [1] 4. The crystal structure of 3 shows the molecule to have a crystallographic inversion centre. Thus cis-trans isomerisation must have taken place during the working up procedure. Alkylation has severe consequences on bond distances and bond angles of the cyclotetraphosphazane ring system, in contrast to M(CO)s complexation at the same positions as shown in a similar case recently [8].
