The title complex has been synthesized with o-acetamidobenzoic acid and 1,10-phenanthroline (phen) in the solvent mixture of water and methanol. It crystallizes (C30H24CdN4O7, M r=666.95) in triclinic space group P1 with a=0.950 89(18) nm, b=1.158 1(2)nm, c=1.497 7(3) nm; α=103.383(3)°, β=104.997(3)°, γ=103.845(3)°, V= 1.4692(5) nm3, Dc = 1.508 g·cm3, Z=2, F(000)=672, R1=0.032 6, wR 2=0.0700. The crystal structure shows that the cadmium atom is coordinated with five oxygen atoms from two o-acetamidobenzoic acids molecules and one water m...
