(6-Chloropyridazin-3-yl)ferrocene.

The asymmetric unit of the title compound, [Fe(C5H5)(C9H6ClN2)], contains two independent mol-ecules in which the cyclo-penta-dienyl rings are almost parallel, making dihedral angles of 2.16 (4) and 2.71 (5), and the dihedral angles between the pyridazinyl and substituted cyclo-penta-dienyl rings are 9.

2-Iodo-4,6-dimethyl-pyrimidine.

In the title compound, C(6)H(7)IN(2), the non-H atoms of the mol-ecule are located on a crystallographic mirror plane; the H atoms of the methyl groups are therefore disordered over two positions of equal occupancy. In the crystal structure, short inter-molecular I⋯N contacts [3.390 (3) Å] are found, linking the mol-ecules into zigzag chains.
