Metal complexes of 21-(4-tert-butyl-benzenesulfonamido)-5,10,15,20-tetraphenyl-porphyrin: Ga(N-p-NSO2C6H4tBu-tpp)(OH), Tl(N-p-NSO2C6H4tBu-tpp)(O2CCF3) and Zn(N-p-NSO2C6H4tBu-tpp) [tpp = 5,10,15,20-tetraphenylporphyrinate]

This work reports X-ray crystals of Ga(N-p-NSO2C6H4tBu-tpp)(OH) (2), Tl(N-p-NSO2C6H4tBu-tpp)(O2CCF3) (3) and Zn(N-p-NSO2C6H4tBu-tpp) (4). The coordination sphere around Tl3+ ion in 3 is a distorted square-based pyramid, whereas for the Ga3+ ion in 2, it is a distorted trigonal bipyramid. The geometry around Zn2+ in 4 is a distorted square planar.
