[Cobalt(II)L-glutamate(H2O)•H2O]∞:: a new 3D chiral metal-organic interlocking network with channels

A monometallic assembly of composition [Cobalt(II)L-glutamate(H2O).H2O](infinity)(I) has been prepared and structurally and magnetically characterized. Assembly I crystallizes in the orthorhombic space group P2(1)2(1)2(1) with a=7.149(9), b=10.468(3), c=11.295(5) Angstrom, V=845.3 Angstrom(3) and Z=4. The crystal structure analysis reveals a three-dimensional network with channels parallel to the a-axis. The observed structure suggests that highly isolated Co(II) cations are present in the solid state structure-a fact verified by the temperature-dependent magnetic susceptibility (298-5 K) which is that of a classical, isolated paramagnet with mu((eff)) ranging from 4.1 to 5.2 BM.
