N2 - A series of manganese(II) amides (1-4), derived from 2,6-diisopropylaniline (H2NAr; where Ar = 2,6-Pri 2C6H3) and its N-silylated derivative H(SiMe3)NAr, has been prepared and characterized. The crystal structure of Mn[N(SiMe3)Ar]2[THF] (2) reveals a monomeric species with a planar three-coordinate Mn(II) center. Crystal data for 2: trigonal (hexagonal axes), a = 30.119(2) Å, c = 10.589(1) Å V = 8319(1) Å3, T = 153 K, space group P 31 (No. 144), Z = 9 (R/Rw = 0.053/0.050). In contrast, Mn3[N(H)Ar]4[N(SiMe3)2]2 · C7H8 (4) is shown to be a novel trinuclear compound held together by nitrogen-bridges. The two terminal Mn(II) atoms have a distorted trigonal planar arrangement of nitrogen donors whereas the central Mn(II) is surrounded by a distorted tetrahedral array of nitrogen donors. Crystal data for 4: orthorhombic, a= 21.301(5) Å b = 17.021(6) Å c = 20.519(7) Å V = 7439(4) Å3, T = 153 K, space group Pbcn (No. 60), Z = 4 (R/Rw = 0.050/0.070).
