[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]∞ (I) has been prepared and structurally and magnetically characterized. Assembly I crystallizes in the orthorhombic space group P212121 with a = 7.149(9), b = 10.468(3), c = 11.295(5) Å, V = 845.3 Å3 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 μ(eff) ranging from 4.1 to 5.2 BM.
