Abstract
The synthesis and physico-chemical characterization of diazido–germanium(IV) and –tin(IV) porphyrins by 1H n.m.r., i.r., u.v.–visible, and mass spectroscopy has been carried out. The crystal structure of diazido (5,10,15,20-tetra-p-tolylporphyrinato)germanium(IV) is described [tetragonal, space group I2d, a= 18.123(1), c= 12.162(2)Å, Z= 4, R= 0.032, R′= 0.034]. The co-ordination polyhedron is an almost perfect octahedron: Ge–N(porphyrin) 1.983(3), Ge–N(azide) 1.963(4)Å.This publication has 3 references indexed in Scilit:
