Abstract

The crystal structure and solution behavior of [(NH3)Pd(1-MeC)3](ClO4)2·H2O, where 1-MeC = 1-methylcytosine, C5H7N3O, is reported. The compound crystallizes in the triclinic system, space group P1̄, with a=8.937(2), b=11.672(3), c=13.871(3) Å, α=65.90(2), β=87.36(1), γ=79.17(2)°, U=1296.6(5) Å3, Z=2. Pd binding is through N3 of the three 1-MeC rings. These nucleobases display a mutual head-tail-head orientation in the solid state. H bonding interactions and relationships with two possible alternative rotamers are discussed.
