Abstract
The reaction of [Mn{N(SiMe3)2}2 (THF)] 1 with 2,2'-bipyridine (2,2'-bipy), 1,10-phenan-throline (1,10-phen) and 4,4'-bipyridine (4,4'-bipy) yields three new complexes: [Mn(2,2'-bipy){N(SiMe3)2}2] 2, [Mn(1,10-phen){N(SiMe3)2}2] 3, and [Mn(4,4'-bipy){N(SiMe3)2}2] · THF 4. The crystal structure of 3 reveals mononuclear species with pseudo-tetrahedral coordinated manganese(II) ions. Crystal data for 3: orthorhombic, a = 1741.0(2), b = 1879.3(3), c = 1967.0(3) pm, V = 6.436(2) nm3, Z = 8, space group Pbca. Compound 4 crystallizes in the monoclinic system, space group P 21/c; the lattice parameters are: a = 2139.5(3), b = 925.30(10), c = 1786.4(2) pm, β = 101.34(1)°, V= 3.4675(7) nm3, Z = 4. The molecular structure of 4 consists of zig-zag infinite chains, with bridging 4,4'-bipyridine groups.Keywords
