The title complex has been synthesized with m-chlorobenzoic acid, 1,10-phenanthroline and cobalt perchlorate anhydrous in the solvent mixture of water and methanol. Crystal data for this complex: triclinic, space group P1, a=0.870 7(3) nm, b=1.284 4(4) nm, c = 1.692 9(5) nm; α=75.430(5)°, β=77.562(5)°, γ=86.346(5)°, V = 1.7894(9) nm3, Dc=1.456 g·cm-3, Z=2, F(000)=806. Final GooF=1.065, R1=0.0684, wR2=0.127 5. The crystal structure shows that the Cobaly ion is coordinated with four nitrogen atoms from two 1,10-phenanthroline molecules and...
