Abstract
The adduct 1,6-diaminohexane-1,1,1-tris(4-hydroxyphenyl)ethane (1/2) is a salt (hexane-1,6-diyldiammonium-4-[1,1-bis(4-hydroxyphenyl)ethyl]phenolate (1/2)), C(6)H(18)N(2)2+ x 2C(20)H(17)O(3)(-), in which the cation lies across a centre of inversion in space group P-1. The anions are linked by two short O-H* * *O hydrogen bonds [H* * *O 1.74 and 1.76 A, O.O 2.5702 (12) and 2.5855 (12) A, and O-H* * *O 168 and 169 degrees ] into a chain containing two types of R(2)2(24) ring. Each cation is linked to four different anion chains by three N-H* * *O hydrogen bonds [H* * *O 1.76-2.06 A, N* * *O 2.6749 (14)-2.9159 (14) A and N-H* * *O 156-172 degrees ]. In the adduct 2,2'-bipyridyl-1,1,1-tris(4-hydroxyphenyl)ethane (1/2), C(10)H(8)N(2) x 2C(20)H(18)O(3), the neutral diamine lies across a centre of inversion in space group P2(1)/n. The tris(phenol) molecules are linked by two O-H* * *O hydrogen bonds [H* * *O both 1.90 A, O* * *O 2.7303 (14) and 2.7415 (15) A, and O-H* * *O 173 and 176 degrees ] into sheets built from R(4)4(38) rings. Pairs of tris(phenol) sheets are linked via the diamine by means of a single O-H* * *N hydrogen bond [H* * *N 1.97 A, O* * *N 2.7833 (16) A and O-H* * *N 163 degrees ].
The study presents three-dimensional hydrogen-bonded frameworks formed with 1,6-diaminohexane and 2,2'-bipyridyl, demonstrating their potential for use in organic electronics and photocatalysis.
