The structure of the title compound, trichloro-2 kappa(3)Cl-(5,10,15,2
0-tetraphenylporphyrinato- 1 ppa(4)N(21,22,)(23,24))rhodium(III)tin(II
)(Rh-Sn), [RhSnCl3(C44H28N4)], consists of well separated units in whi
ch the Rh atom is five-coordinate at the center of a square-pyramidal
polyhedron with the Sn atom at the top. The macrocylic unit is planar
with the Rh atom displaced by only 0.02 Angstrom from the ring plane.
The Rh-Sn bond length is 2.450 (1) Angstrom.
