The Crystal Structure of cis ‐ and trans ‐N‐ iso ‐Propylamidodimethyl Indium, [(CH 3 ) 2 In‐N(H) i C 3 H 7 ] 2 According to the X‐ray structure determination [(CH 3 ) 2 In‐N(H) i C 3 H 7 ] 2 (prepared from InMe 3 (Me = CH 3 ) and H 2 N i Pr ( i Pr = CH(CH 3 ) 2 ) crystallizes in the monoclinic space group P2 1 /n with 3 dimeric trans as well as 3 dimeric cis isomers per unit cell. The centrosymmetric form has a planar In 2 N 2 core with In—N bonds of 222.1(4) and 222.9(5) pm, respectively, the skeleton of the cis isomer with In—N bonds of 221.4(4) pm is slightly folded (13.7°). Some 1 H, 13 C NMR, IR, and Raman data are reported.
