| Abstract: | A copper complex or kinetin(N6-frufruryladenine), a plant growth regulator, has been synthesized. Crystal Data: Monoclinic space group C2/c with cell dimensions a=11.711(2)Å, b= 7.930(2)Å, c=28.672(6)Å, b= 101.64(2)°, Z=8 and R=0.0806. Cu2+ exhibits a distorted octahedral geometry - four chlorides and two N9 atoms of the adenine moiety achieving the octahedral environment around copper. The adenine moiety exists as the N3 protonated N7-H tautomer. Protonation has enhanced the internal angles at the site or protonation. Based on charge neutrality, N1 is also assigned a proton with 0.5 occupancy. There is a paucity or data on molecular dimensions of adenine moiety with this type of simultaneous N3, N7 protonation and N9 coordination. The N6 substituent is distal to N7. The dihedral angle between the adenine moiety and the furfuryl ring is 63.2(3)°. The coordination has not significantly affected the inherent conformation or the kinetin moiety even under acidic conditions. |
