Cu II complex with 1,3,5-trimethylpyrazole (1,3,5-TMePz) trans-[Cu(1,3,5-TMePz)2(NO3)2] has been prepared and studied by X-ray diffraction, vibrational and electronic spectroscopy. The complex crystallizes in the orthorhombic crystal system, P212121 space group with lattice parameters:a = 7.6784(8),b = 13.5856(11), c = 16.3372(13) capital A ring, V = 1704.2(3)capital A ring 3 and Z = 4. The hydrogen bond system stabilizes the crystal structure. Two nitrogen atoms of 1,3,5-TMePz and four oxygen atoms of chelating NO-3 groups form a trans-CuIIN2O2O2 ' chromophore.
