Supramolecular chemistry of amine-phenol adducts; novel three-dimensional framework structures in adducts of bis(2-aminoethyl)amine with 4,4 '-sulfonyldiphenol, 1,1,1-tris(4-hydroxypenyl)ethane and 3,5-dihydroxybenzoic acid,and in the methanol-solvated adduct of tris(2-aminoethyl) amine with 4,4 '-biphenol

Bis(2-aminoethyl)amine-4,4'-sulfonyldiphenol (1/3) (1) (orthorhombic Pccn w ith Z' = 0.5) is a salt, [HN(CH2CH2NH3)(2)](2+). [O2S(C6H4O)(2)](2-).[O2S(C 6H4OH)(2)](2), containing both dianionic and neutral bis-phenol units, The neutral and anionic bis-phenol units are linked by strong O- H...O- hydroge n bonds to form ladders built from R-4(4)(48) rings: each ladder is interwo ven with its two nearest neighbours to form a continuous two-dimensional sh eet, The amine cations play two roles: they link each ladder to its two nex t-nearest neighbours by means of N-H...O hydrogen bonds and they also link each sheet to the two neighbouring sheets, again via N-H...O hydrogen bonds , thus generating a three-dimensional framework, Bis(2-aminoethyl)amine-l,1 ,1-tris(4-hyclroxyphenyl)ethane-methanol (1/4/1) (2) (triclinic P (1) over bar with Z' = 0.5) consists entirely of neutral Fragments The tris-phenol u nits are linked by O-H...O hydrogen bonds into molecular ladders built from R-4(4)(48) rings: these ladders are linked by the amine units, firstly int o sheets and thence into a three-dimensional framework. Bis(2-aminoethyl)am ino-3,5-dihydroxybenzoic acid (1/2) (3) (monoclinic P2(1)/c with Z' = 1) is a salt [HN(CH2CH2NH3)(2)](2+).[{(HO)(2)C6H3COO}(-)](2). The 3,5-dihydroxyb enzoate anions are linked by O-H...O hydrogen bonds into interwoven and cro ss-connected (001) sheets linked by further O-H...O hydrogen bonds into a t hree-dimensional framework, The (001) sheets are further linked by ladders formed Front both cat-ions and anions. Tris(2-aminoethyl)amine-4,4'-bipheno l-methanol (1/3/1), (4) (monoclinic P2(1)), is a salt[{(H2NCH2CH2)(2)-N(CH2 CH2NH3)}(+)](2).[OC6H4C6H4O](2-).[HOC6H4C6H4OH](5.-) [MeOH](2), with Z' = 1 . The asymmetric unit, containing ten independent molecular components, car t be regarded as a supermolecule held together by a total of 13 independent hydrogen bonds, of O-H...O, O-H...N and N-H...O types. The supermolecules are linked by O-H...O and N-H...O hydrogen bonds into two-dimensional sheet s, generated by translation; further N-H...O hydrogen bonds around the 2, s crew axes link neighbouring sheets together into a three-dimensional framew ork.
