The crystal and molecular structures of four-coordinate silver(II) and zinc(II) tetraphenylporphyrinates have been determined. Both complexes crystallize in the triclinic system and are isomorphous with the triclinic modification of the parent macrocycle HjTPP. Bond distances in the centrosymmetric coordination groups of both complexes are found to be statistically nonequivalent. Features of the crystal packing of the compounds suggest that this inequivalence arises from asymmetric lattice packing. The average Ag-N distance is 2.092 Á (individual values 2.082 (3) and 2.101 (3) Á), and that for Zn-N is 2.037 Á (individual values 2.045 (2) and 2.029 (2) A). Crystal data for AgTPP: triclinic, a = 10.503 (2) A, b = 12.485 (2) A, c = 6.351 (2) A, a = 97.72

A microporous metal-organic framework 1, Cu(R-GLA-Me)(4,4'-Bipy) 0.5.0.55H 2O (R-GLA-Me = R-2-methylglutarate, 4,4'-Bipy = 4,4'-bipyridine), with a primitive cubic net was synthesized and characterized. With pores of about 2.8 x 3.6 A, the activated 1a exhibits exclusive adsorption of water over methanol in a binary water-methanol (1:1) liquid mixture.
