A new 3-D Gd-Cu heterometallic polymer [Gd₂Cu₃(bpy)₂-(ip)₆]·6H₂O with a non-interpenetrated α-Po net

A new 3-D porous Gd-Cu heterometallic polymer [Gd2Cu3(bpy)(2)(ip)(6)]center dot 6H(2)O (1) (bpy = 2,2'-bipyridine, H(2)iP = isophthalic acid) has been hydrothermally synthesized and structurally characterized. Compound 1 crystallizes in the triclinic space group P (1) over bar and displays a 3-D non-interpenetrated alpha-Po network with 1-D channels filled transversely by the hexa-nuclear chain-like (H2O)(6). The EPR and thermal stability of 1 were investigated.
