title: 2,2'-[1,1'-(Decane-1,10-diyldioxy-dinitrilo)diethyl-idyne]diphenol.
abstract: The salen-type bis-oxime title compound, C(26)H(36)N(2)O(4), lies about a crystallographic inversion centre. Classical intra-molecular O-H⋯N hydrogen bonds generate two S(6) ring motifs. In the crystal structure, pairs of weak inter-molecular C-H⋯O hydrogen bonds link adjacent mol-ecules into an infinite one-dimensional supra-molecular structure.
