Abstract

The salts comprised of picric acid [(OH)(NO2) 3C6H2] and different ditopic pyrazoles PzR1, R2H (where R1= R2= H for 1, R1= R2= Me for 2, R1= Ph, R2= Me for 3) and 3, 3′, 5, 5′- tetramethyl-4, 4′-bipyrazole (Me4bpz) 4 are reported. Due to presence of different substituents on pyrazole, each salt contains infinite three-dimensional structure held together by primary N–H… O, O–H… N, O–H… O hydrogen bonds and secondary C–H… ...
