The growth of crystals of the coordination polymer [CuC 12 H 8 N 4 O 2 ] n with one‐dimensional magnetic properties is reported. Several approaches have been proposed and tested in order to diminish the growth anisotropy and plate‐like crystals of an area measuring up to 250×100 μm 2 were grown. The structure and the composition of the crystals are slightly modified with respect to that of earlier synthesized powder. Instead of the water free triclinic phase a monoclinic phase, intercalated by water molecules, forms. In the new modification, the polymer chain layers are bound together by a network of hydrogen bonds, which are stronger than the usual Van der Waals interactions in the triclinic phase. The crystal morphology is plate‐like instead of the earlier obtained spherulitic needles. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
