Abstract
The asymmetric unit of the title complex, [MnI2(C8H6N4)2], contains one half of a neutral MnII complex, with the entire molecule completed by the application of twofold symmetry. The MnII ion is six-coordinated in a distorted octahedral environment defined by four N atoms of the two chelating 2,2′-bipyrimidine (bpym) ligands and two I− anions in a cis-N4I2 coordination geometry. The dihedral angle between the least-squares planes of the two bpym ligands (r.m.s deviation for all non-H atoms = 0.063 Å) is 85.04 (6)°. In the crystal, complex molecules are connected by C—H⋯N and C—H⋯I hydrogen bonds, forming a three-dimensional network. Molecules are stacked in columns along the a axis. Along the c axis, successive molecules stack in the opposite directions.
