Abstract

Crystallisation of flexible dipyridyl ligands with Cd(NO3)(2). 4H(2)O. Cd(ClO4)(2). xH(2)O or Cd(NO3)(2). 4H(2)O and KSCN gives co-ordination networks of composition [Cd(ClO4)(2)(Py2C3H6)(2)(H2O)(2)]. Py2C3H6 1 (Py2C3H6 =1,3-bis(4-pyridyl)propane); [Cd(ClO4)(2)(Py2C2H4)(3)] 2 (Py2C2H4 =1,2-bis(4-pyridyl)ethane); [Cd(NCS)(2)(Py2C3H6)] 3; [Cd-2(NO3)(4)(o-C6H4(CH(2)CH(2)4-Py)(2))(4)] 4 (o-C6H4(CH2CH2Py)(2) =1,2-bis[2-(4-pyridyl)ethyl] benzene and [Cd(NO3)(2)(PyCH2CH2CH=CHCH2CH2Py)(3)] 5 (PyCH2CH2CH=CHCH2CH2Py =1,6-bis(4-pyridyl)hex-3-ene). The compounds were characterised by X-ray single crystal diffraction studies which revealed the presence of different polymeric motifs. Structures I and 5 consist of I-D polymeric chains, structure 4 consists of a 2-D polymeric network and structure 3 is a 3-D polymeric network. None of these exhibit lattice interpenetration. However structure 2 consists of three identical but independent interpenetrating 3-D lattice networks. (C) 2001 Elsevier Science Ltd. All rights reserved.
