In 4 and 5 each (R(1))(R(2))(PhC=C)P building block is datively bonded to a M(I)OSO(2)CF(3) unit. By the formation of M(I)OSO(2)CF(3)M(I) bridges (M = Cu, Ag) dimers are formed. The X-ray structure analysis of 5a is reported. Crystals of 5a are monoclinic, space group P2(1)/n with cell constants a = 1722.3(5), b = 1099.2(4), c = 1884.5(6) pm, beta = 107.21(2)degrees, V = 3409(2) X 10(6) pm(3) and Z = 2. » weiterlesen» einklappen
