The crystal structures of the title complexes, (1) and (2) respectively, are reported. Complex (1) crystallises in the orthorhombic space group Pca21 with a= 20.399(5), b= 8.177(6), and c= 10.699(4)Å. Crystals of the complex (2) are triclinic, space group P, with a= 10.219(3), b= 10.436(3), c= 8.452(2)Å, α= 91.83(3), β= 111.28(4), and γ= 101.30(3)°.
