摘要
A new high-spin five-co-ordinated manganese(II) complex [Mn(tdpea)I]BPh4.2CH2Cl2 with the tripod ligand tdpea = N(CH2CH2PPh2)3 has been prepared and characterized. Its molecular structure has been determined by single-crystal diffraction methods: monoclinic, space group P2(1)/n, a = 34.511 (9), b = 17.461 (4), c = 10.753(3) -angstrom, beta = 95.45(2)-degrees, and Z = 4. The metal atom is co-ordinated by one nitrogen and three phosphorus atoms of the tripod ligand and by the iodine ligand. The co-ordination geometry of the cation may be considered halfway between a trigonal bipyramid and a tetrahedron with the P-Mn-I angles averaging 104.3(5)-degrees and the Mn-N distance 2.634(9) angstrom.
