title: 3,4,7-Trimethyl-2-(4-methyl-phen-yl)-2H-pyrazolo-[3,4-d]pyridazin-5-ium thio-cyanate.
abstract: 1,1'-[5-Methyl-1-(4-methyl-phen-yl)-1H-pyrazole-3,4-di-yl)di-ethan-one condenses with thio-semicarbazide in the presence of acetic acid to form the title salt, C(15)H(17)N(4) (+)·NCS(-). The fused-ring system of the cation is almost planar (r.m.s. deviation = 0.020 Å) and the aromatic substituent is aligned at an angle of 48.2 (1)° with respect to the mean plane of the fused-ring system. The N atom at the 5-position is protonated and forms a N-H⋯N hydrogen bond to the thio-cyanate cointer-ion.
