On heating a crystal of the one-dimensional coordination polymer catena-poly[[diaqua(sulfato)copper(II)]-2-glycine] to 435 K in an oven, its aspect changed from blue to a very pale blue. Crystal structure analysis indicated that it had undergone a single-crystal to single-crystal (SCSC) solid-state transformation, losing two water molecules and forming a two-dimensional coordination polymer, viz. poly[2-glycine-4-sulfato-copper(II)].
