چکیده
In the mol-ecule of the title compound, C(23)H(20)O(3), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The central benzene ring makes dihedral angles of 80.17 (8) and 16.99 (7)°, respectively, with the benz-yloxy and hy-droxy-methyl phenyl rings. In the crystal, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds to form dimers. The dimers are connected by C-H⋯O hydrogen bonds and C-H⋯π inter-actions to form columns down the b axis.

A Study on the Synthesis and Biocidal Efficacy of Certain Random Copolyesters Containing Chalcone Moiety
A series of four random copolyesters were synthesized by the polycondensation of a chalcone diol by making use of two diacid chlorides namely terephthaloyl chloride and succinyl chloride. The four chalcone diols involved are (2E)-1,3-bis(4-hydroxyphenyl)prop-2-en-1-one, (2E)-1-(4-hydroxyphenyl)-3-(4-hydroxy-3-methoxyphenyl)-prop-2-en1-one, (2E)-1-(4-hydroxy-3-methoxyphenyl)-3-(4-hydroxyphenyl)-...

In the crystal of compound (I), C14H11ClOS, mol-ecules are linked by C-H⋯O hydrogen bonds to form simple C(5) chains. Compound (II), C26H22O, crystallizes with Z' = 2 in space group P-1; one of the mol-ecules is fully ordered but the other is disordered over two sets of atomic sites having occupancies 0.644 (3) and 0.356 (3). The two disordered components differ from one another in the orientat...
