cqvip:MnCl2 (C12,H8N2)2, Mr= 486. 26, monoclinic, P21,/c, a= 9. 461 (5),b= 15. 20(1), c= 14. 514(2) A, β=98. 82(3)°, V=2062(2) A3, Z=4, Dc= 1. 57g/cm3. λ(MoKα) = 0. 71073 A, μ(MoKα) = 0. 895 mm-l, F (000) = 988, T= 296K. Final R= 0. 043, Rw= 0. 053 for 2569 observed reflections. The Mn atom is co-ordinated by two Cl anions and four N of two phenanthroline (phen) molecules, forming a distorted octahedron. Two Mn--Cl bond lengths are 2. 437(2) and 2. 449(2) A,respectively. The Mn--N bond lengths vary from 2. 290(3) to 2. 367 (4) A。 The dihedral angle between two phen best planes is 90. 4°.
