摘要：
Mn(II) complexes Mn[HB(pz)(3)](2) (1) (pz = pyrazole) and Mn[HB(3,5-Me-2-pz)(3)](2) (2) have been obtained by the reaction of Mn(OOCCH3)(2) with NaHB(pz)(3) and NaHB(3,5-Me-2-pz)(3) in MeOH, respectively. The two complexes (1) and (2) were characterized by IR, elemental analyses, and x-ray diffraction. Complex (1) crystallizes in the space group C2/c, a = 18.971(3) Angstrom, b = 13.700(3) Angstrom, c = 19.056(3) Angstrom, beta = 11 1.378(10), V=4612.0(13) Angstrom(3), Z = 2. Complex (2) crystallizes in the space group R-3, a = 10.9832(18) Angstrom, b = 10.983(2) Angstrom, c = 24.785(3) Angstrom, gamma = 120degrees, V = 2589.3(7) Angstrom(3), Z = 3. X-ray structure analysis has shown that the complexes (1) and (2) all are monomeric neutral complexes, and possess similar coordination modes around the metal Mn centers. In addition, some related bonding distances, angles, and structural properties are discussed.
