Abstract

Two new cobalt(III) and zinc(II) complexes, [Co(L1)2 (H2O)] · ClO4 (I) and [Ni(L2)2 (H2O)2] · 2ClO4 (II), where L1 is the deprotonated form of 5-methoxy-2-[(2-morpholin-4-ylethylimino)methyl]phenol, and L2 is the zwitterionic form of 2-[(2-isopropylaminoethylimino)methyl]-5-methoxyphenol, were synthesized and structurally characterized by elemental analyses, IR spectra, and single-crystal X-ray diffraction. The crystal of I is monoclinic: space group P21/c, a = 11.1512(4), b = 28.2424(11), c = 10.9655(4) A, β = 95.746(2)°, V = 3436.1(2) A3, Z = 4. The crystal of II is triclinic: space group P21/c, a = 8.1441(2), b = 10.4531(3), c = 10.8849(3) A, α = 84.0240(10)°, β = 76.9800(10)°, γ = 74.2280(10)°, V = 867.92(4) A3, Z = 1. Complex I consists of a mononuclear cobalt(III) complex cation and a perchlorate anion. Complex II consists of a crystallographic centrosymmetric mononuclear nickel(II) complex cation and two perchlorate anions. Each metal atom in the complexes is in an octahedral coordination.
