CRYSTAL-STRUCTURE AND 2-STAGE HYDROLYSIS OF O(MESO-TETRA(4-METHOXYPHENYLPORPHYRINATO))TIN(IV), SN(TMPP)(OME)(2)

In this work, we determine the crystal structure of o(meso-tetra(4-met hoxyphenylporphyrinato))tin(IV), Sn(tmpp)(OMe)(2) (1). Experimental re sults indicate that the tin atom has an octahedral geometry. The geome try around the tin center has Sn(1)-O(5) = 2.020(6), Sn(1)-O(6) = 2.00 3(7) Angstrom and an average Sn(1)-N = 2.10(1) Angstrom. The two metho xo groups are unidentately coordinated to the tin(IV) atom. Two-stage hydrolysis of Sn(tmpp)(OMe)(2) in CDCl3 was observed by H-1 and C-13 N MR spectroscopy. Compound (1) crystallizes in the space group P2(1)/n with a = 14.7492(1), b = 19.2022(3), c = 16.0806(2) Angstrom, beta = 9 4.104(1)degrees and Z = 4.
