摘　　要：The reaction of N-n-Bu4MnO4 with Mn(Oac) 2 · 4H2O and butenoic acid in nonaqueous solvents leads to the formation of the complex [Mn3O(O2CCH = CHCH3) 6(py) 3] ClO4 · py (1). The crystal structure was determined.The complex crystallizes in hexagonal, space group P63/m, unit cell parameters, a = 1. 2456(1)nm, b = 1. 2456(1) nm, c = 1. 8741(1) nm, V=2. 5181(3) nm3, Z =2, and final R1 =0. 0565, wR2 =0. 1465. Variable tem-perature solid tate magnetic susceptibility study shows that the complex [Mn3O(O2CCH = CHCH3)6(py)3] ClO4 (2) has an antiferromagnetic exchange interaction.The reaction of N- n-Bu4MnO4 with Mn(OAc) 2, 4H20 and butenoic acid in nonaqueous solvents leads to the formation of the complex [Mn3O(O2CCH = CHCH3)6(py) 3] ClO4. py (1).
