The X‐ray structures at 120 K of C 6 H 5 SeO 2 N(CH 3 ) 2 ( 1 ) and C 6 H 5 SeO 2 NHCH 3 ( 2 ) were determined from single crystal data, the structure of C 6 H 5 SeO 2 NH 2 ( 3 ) was determined from a twin. The structure of ( 1 ) is composed of isolated molecules, that of ( 2 ) of dimers via H‐bonds and the structure of ( 3 ) forms infinite chains. The SeN lengths are 1.815(2) Å for ( 1 ), 1.791(2) Å for ( 2 ), and 1.781(6) Å for ( 3 ).
