Popis:	Two heterospin complexes [Cu(NIT3Py)(cda)H2O]·H2O (1) and [Cu(NIT2Py)(cda)H2O]·H2O·CH3OH (2) with CuII ions and pyridyl-substituted nitronyl nitroxide radicals (NITxPy = 2-(x′-pyridyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide, x = 3, 2; H2cda = 4-hydroxy-pyridine-2,6-dicarboxylic acid) were synthesized and characterized structurally and magnetically. The single crystal structures show that the two complexes are both two-spin complexes, in which the different radicals make the two complexes have different hydrogen bonding interactions to form 2D and 1D supramolecular network for complexes 1 and 2, respectively. The magnetic measurements indicate that complexes 1 and 2 both exhibit antiferromagnetic interactions between CuII and radicals.
