Die Kristallstruktur voncis- undtrans-N-iso-Propylamidodimethylindium, [(CH3)2In-N(H)iC3H7]2

According to the X-ray structure determination [(CH3)(2)In-N(H)(C3H7)-C-l](2) (prepared from InMe3 (Me = CH3) and (H2NPr)-Pr-l (Pr-l = CH(CH3)(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 In2N2 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 (13.7degrees). Some H-1, C-13 NMR, IR, and Raman data are reported.
