The molecular structure of the neutral mononuclear title complex, [Mn(NCS) 2 (C 12 H 8 N 4 O) 2 (H 2 O) 2 ], is centrosymmetric; the Mn II atom lies on an inversion center and is sixcoordinate (MnN 4 O 2 ), with an octahedral geometry comprising two trans monodentate 2,5-di-3-pyridyl-1,3,4oxadiazole
In the title molecule, C 26 H 23 Cl 2 NO 3 S, the tetrahydropyridine ring adopts a half-chair conformation. Intramolecular O-HÁ Á ÁO hydrogen bonding generates an S(6) ring motif. Intermolecular N-HÁ Á ÁCl, C-HÁ Á ÁCl and C-HÁ Á ÁS hydrogen bonding generates primary graph-set motifs C(8), C(11) and
In the crystal structure of the title compound, C 10 H 11 ClN 2 O 2 , the 1,3-diaza ring exists in the skew-boat conformation. Supramolecular aggregation is effected by the formation of an infinite two-dimensional network of O-HÁ Á ÁO and N-HÁ Á ÁO interactions.
Supramolecular assembly of the title compound, C 12 H 14 Cl-FN 2 O, is primarily governed by NÐH + Á Á ÁCl À and CÐHÁ Á ÁO interactions, and a putative CÐHÁ Á ÁF interaction. The piperidine ring assumes a chair conformation, with the substituted benzisoxazole ring in an equatorial position.
