Synthesis of co-ordination networks selecting from either (R, R), (S, S) and (R, S)-1,4- or -1,3-bis[2-(4-pyridyl)-2-methylethyl] benzene and a discrete complex from 1,4-bis[2-(3-pyridyl)-2-methyl-cis-ethenyl)]benzene

Abstract

Three distinct 2-D coordination networks with (4,4) topology where obtained from solutions containing a chiral ligand L and the appropriate metal salt, [CdL2(NO3)2](n)center dot H2O where L = (R, R)-, (S, S)- and (R, S)-1,4-bis[2-(4-pyridyl)-2-methyl)ethyl] benzene (0.25 : 0.25 : 0.5), [CdL2(H2O)(2)](n)center dot L'center dot(H2O)(2)center dot(ClO4)(2) where L = (R, R)-, (S, S)- and (R, S)-1,4-bis[2-(4-pyridyl)-2-methyl)ethyl] benzene (0.25 : 0.25 : 0.5) and [ML2(H2O)(2)](n)center dot L center dot(NO3)(2) where M = Co or Ni and L = (R, S)-1,4-bis[2-(4-pyridyl)-2-methyl)ethyl]benzene). These nets display different geometrical features including different modes of connection of L units by the four-connected metal centre. In addition, the infinite chain structure [CdL2(NO3)(2)](n)center dot H2O where L = (R, S)-1,3-bis[2-(4-pyridyl)-2-methyl)-ethyl] benzene whose metal centres are also four-connected and the finite molecular structure [CuL2(NO3)(2)]center dot H2O with L = 1,4-bis[2-(3-pyridyl)-2-methyl-cis-ethenyl)]benzene) were obtained.
