Popis:	The macrocyclic complexes M(L)X2(H2L = 5,14-dihydro-6,8,15,17-tetramethyldibenzo[b,I][1,4,8,11]- tetraazacyclotetradecine; M = Sn, X = Cl, Br or I; M = Ge, X = Cl; M = Si, X = Cl) have been prepared by the reaction of the tetrahalide MX4 with H2L (M = Sn or Ge) or Li2L (M = Si) under mild conditions. Treatment of Sn(L)Cl2 with AgNO3 produces Sn(L)(NO3)2′ which in turn gives Sn(L)F2 upon reaction with [NBu4]F. X-Ray crystal structures of Sn(L)Cl2 and Sn(L)(NO3)2·MeCN reveal that the complexes retain the characteristic saddle-shaped configuration of the ligand but have adopted a trans geometry.
