摘要：
The molecular structure of a novel manganese complex with 4-(pyridine-2)-1,2,4-triazole has been determined by X-ray analysis. Crystals are triclinic, space group P (1) over bar, with a = 10.397(4), b = 12.033, c = 13.920(5)Angstrom, alpha=115.325(5), beta=90.449(6), gamma=109.379(7)degrees, V=1461.8(9)Angstrom(3), Z=2, R1=0.0569, wR2=0.1113. The manganese atom lies in a distorted octahedral environment. Two ligand molecules coordinate axially and two cis-oriented thiocyanate anions and cis-oriented water molecules coordinate to the metal centre. The crystal is stabilized by intramolecular pi-pi stacking and hydrogen bonding. Magnetic measurements show the complex is a high-spin species in the 77-300 K range.
