1.  N-Phenyl­morpholine-4-carboxamide 
In the title compound, C11H14N2O2, the urea-type NC=ON moiety [planar to within 0.0002 (13) Å] is inclined to the phenyl ring by 42.88 (8) Å, and the morpholine ring has a chair conformation. In the crystal, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into infinite chains in [001].

2.  Ethyl 2-amino-6-benzyl-4,5,6,7-tetra­hydro­thieno[2,3-c]pyridine-3-carboxyl­ate 
In the title compound, C17H20N2O2S, the tetra­hydro­pyridine ring adopts an envelope conformation with the N atom at the flap position; the phenyl ring makes a dihedral angle of 81.06 (10)° with the thio­phene ring. The amino group links with the carbonyl O atom via intra­molecular N—H⋯O hydrogen bonding, forming a six-membered ring. In the crystal, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into infinite chains running along the b axis.

3.  3-Phenyl-2-(pyrrolidin-1-yl)-5,6-dihydro-8H-thio­pyrano[4′,3′:4,5]thieno[2,3-d]pyrimidin-4(3H)-one 
In the title compound, C19H19N3OS2, the thio­pyran ring adopts a twist-chair conformation and the pyrimidinone unit is essentially planar, with a mean deviation of 0.0497 Å. The thio­phene ring is essentially planar with a maximum deviation of 0.024 (2) Å, while the pyrrolidine ring exhibits an envelope conformation. The pyrimidinone and thio­phene rings are almost coplanar, forming a dihedral angle of 6.31 (15)°, while the dihedral angle between the mean planes of the phenyl ring and the pyrimidinone ring is 68.13 (10)°. In the crystal structure, adjacent mol­ecules are linked by C—H⋯O hydrogen bonds, forming a two-dimensional network in the ac plane.

4.  Bis(2,2′-bi-1H-imidazole-κ2 N 3,N 3′)(thio­cyanato-κN)copper(II) chloride 
In the title salt, [Cu(NCS)(C6H6N4)2]Cl, the CuII atom adopts a five-coordinated square-pyramidal geometry consisting of an N atom from a thio­cyanate anion and four N atoms from two chealting biimidazole ligands. The thio­cyanate ligand occupies the axial position and is, like the CuII centre, located on a mirror plane. The cation and anion are linked into a linear chain by N—H⋯S and N—H⋯Cl hydrogen bonds.

5.  1-[1-(Hydroxy­imino)eth­yl]-N-(2-methoxy­phen­yl)cyclo­propane­carboxamide 
The title compound, C13H16N2O3, adopts an E configuration with respect to the C=N bond and an intra­molecular N—H⋯N hydrogen bond results in the formation of a six-membered ring. In the crystal, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into a chain propagating along the b axis. Very weak π–π stacking inter­actions [centroid–centroid distance = 4.18 (2) Å] may further consolidate the packing, forming a two-dimensional supra­molecular network.

6.  3-Phenyl-2-(piperidin-1-yl)-3,5,6,8-tetra­hydro-4H-thio­pyrano[3′,4′:2,3]thieno[5,4-d]pyrimidin-4-one 
In the title compound, C20H21N3OS2, the piperidinyl ring has a distorted chair conformation. Weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers. The crystal packing exhibits short inter­molecular S⋯S distances of 3.590 (2) Å.

7.  catena-Poly[[(1,12,15,26-tetra­aza-5,8,19,22-tetra­oxa-3,4:9,10:17,18:23,24-tetra­benzocyclo­octa­cosane-κ4 N 1,N 12,N 15,N 26)nickel(II)]-μ-terephthalato-κ2 O 1:O 4] 
In the title compound, [Ni(C8H4O4)(C36H44N4O4)]n, the NiII atom is coordinated in a distorted octa­hedral geometry by the four N atoms of the 1,12,15,26-tetra­aza-5,8,19,22-tetra-oxa-3,4:9,10:17,18:23,24-tetra­benzocyclo­octa­cosane ligand and two O atoms from the terephthalate dianions. The NiII atoms, which lie on inversion centres, are linked via terephthalate ligands to form a chain structure along [101]. The structure is stabilized by three intra­molecular and one inter­molecular N—H⋯O hydrogen bonds.

8.  (E)-N′-(Furan-2-ylmethyl­ene)-4-(quinolin-8-yl­oxy)butanohydrazide 
In the title mol­ecule, C18H17N3O3, the dihedral angle between the mean planes of the furan ring and the quinoline group is 77.4 (2)°. In the crystal structure, inter­molecular N—H⋯N hydrogen bonds link the mol­ecules into centrosymmetric dimers.

9.  Bis(acetyl­acetonato-κ2 O,O′)(methanol-κO)(thio­cyanato-κN)manganese(III) 
In the title complex, [Mn(C5H7O2)2(NCS)(CH4O)], the MnIII atom has a slightly distorted octa­hedral coordination formed by five O atoms and one N atom. The equatorial positions are occupied by four O atoms of two acetyl­acetonate ligands, while the axial positions are occupied by the N atom of the thio­cyanate anion and the O atom of the methanol mol­ecule. In the crystal structure, complex mol­ecules are linked by an inter­molecular O—H⋯S hydrogen bond, forming a chain running along [101].

In the crystal structure of the title compound, [Co(C2H4NO2)(C9H6NO)2]·CH3OH, the CoIII atom is chelated by two quinolin-8-olate and one glycinate anions in a distorted octa­hedral coordination geometry. The five-membered chelating glycinate ring assumes an envelope conformation. The complex mol­ecules are assembled by inter­molecular N—H⋯O hydrogen bonding.
