Abstract
Abstract An X-ray study of (O-Ge)-chelate 1-(dimethylchlorogermylmethyl)pyrrolidone-2 ( 1 ), 1-(dimethylchlorogermylmethyl)piperidine-2 ( 2 ), (N-Ge)-chelate O -(dimethylchlorogermylmethyl)-δ-valerolactim ( 3 ), and 2-(chlorodimethylgermylmethylthio)pyrrolidine-1 ( 4 ) has been carried out ( R = 0.033, 0.062, 0.097 and 0.048 for 1241, 2351, 1242 and 1838 reflections, respectively). The Ge atom has a distorted trigonal-bipyramidal [3 + 2] coordination with the axial Cl and O atoms in 1 and 2 or Cl and N atoms in 3 and 4 . The axial distances are Ge-Cl 2.324(2), 2.354(2), 2.458(8) and 2.566(2) A, Ge ← O 2.311(4) and 2.194(2), Ge ← N 2.148(18) and 2.064(5) A in 1 – 4 respectively. Correlation between structural parameters of the compounds of five- and four-coordinated germanium have been considered.
