It belongs to triclinic crystal system, P1- space group with a=0.955 02(19) nm, 6 = 1.323 4(3) nm, c = 1.515 7(3) nm, a=68.95(3)°, β=77.33(3)°, γ=81.92(3)°, V=1.740 3(6) nm3, Z=2. The manganese (Ⅱ) ions in the complex are 6-coordinated and 7-coordinated. The Mn (Ⅱ) ions of complex 1 are connected by pztc and phen, resulting in a 1D chain. Variable temperature magnetic susceptibility measurements reveal the existence of antiferromagnetic interactions in the complex 1. CCDC: 694108.
