The two title complexes were synthesized by reaction of o-phenanthroline (phen), N-p-tolysulfonytaunne(TsTausH) and transition metal picrates in water-ethanol solution, which were characterized by elemental analysis, IR spectroscopy and X-ray diffraction. Complex 1 crystallizes in the monoclime space group Cc with cell parameters: a=2.917 6(4) nm, b=1.041 48(15) nm, c=2.128 7(3) nm, beta=126.162(3)degrees, and V=5.222 1(13) nm(3), Z=4, D-c=1.486 g center dot cm(-3), mu=0.602 mm(-1), F(000)=2440; Complex 2 crystallizes in the monoclinic space group P2(1)/c with cell parameters: a = 1.113 70(16) nm, b=2.4726(4) nm, c=1.185 87(18) nm, 6=93.355(3)degrees, and V=3.2600(8) nm(3), Z=4, D-c=1.540 g center dot cm(-3), mu=0.934 mm(-1), F(000)=1556. The capacities of coordination to difference atoms were discussed for the two complexes.
