The mol­ecules of the title bis­(thio­morpholine) adduct of bis­(1,3-diphenyl­propane-1,3-dionato)cobalt(II), [Co(C15H12O2)2(C4H8NS)2], in the crystal structure are positioned on an inversion center at the inter­section of a twofold rotation axis and a perpendicular mirror plane. The two thio­morpholine ligands bond to the octahedral cobalt(II) ion in the axial coordination sites (trans configuration).

In the title complex, [Ni(C10H9O2)2(C10H17N)2], the Ni atom, which occupies a special position at an inversion centre, has an octa­hedral environment formed by four O atoms of two chelate benzoyl­acetonates [Ni—O 2.0409 (16) and 2.0187 (16) A, and O—Ni—O 90.36 (6)°] and two N atoms of the adamantylamine ligands [Ni—N = 2.176 (2) A]. The amine H atoms of the adamantylamine ligands do not participate in any hydrogen bonds, due to their steric shielding and the lack of accessible acceptors.

In the reaction of bis(1,3-di­phenyl-1,3-propane­dionato)­oxovanadium(IV) with pyridine, a 1:1 adduct is formed, viz bis(1,3-di­phenyl-1,3-propane­dionato-κ2O,O′)­oxo­(pyridine-κN)­vanadium(IV), [V(C15H10O2)2O(C5H5N)]. The V atom is surrounded by one pyridine ligand, two 1,3-di­phenyl-1,3-propandionate (dbm) ligands and one oxo group. The complex exhibits a distorted octahedral coordination, with the oxo group and pyridine ligand in a cis configuration. Pairs of mol­ecules of the adduct are connected by an intermolecular C41—H41⋯O1(−x, 2 − y, 1 − z) contact of 3.171 (3) A and thus form dimers in the solid state.

In the reaction of bis(1-phenyl­butane-1,3-dionato)­nickel(II) with di­methyl sulfoxide, the adduct bis­(di­methyl sulfoxide)­bis(1-phenyl­butane-1,3-dionato)­nickel(II), [Ni(C10H9O2)2(C2H6OS)2], is formed, in which two di­methyl sulfoxide (DMSO) mol­ecules are coordinated to the Ni atom through their O atoms in a trans arrangement. The compound crystallizes in space group P21/a with the Ni atom lying on a center of inversion. The coordination polyhedron around the Ni atom is a distorted octahedron. The chelate ring deviates slightly from planarity. The Ni—O bond distance to the DMSO O atom is slightly longer than that to the 1-phenyl­;butane-1,3-dionate ligand. In the crystal structure, two-dimensional frameworks are formed by C–H⋯O interactions.

In the adduct bis(1-phenyl-1,3-butanedionate)­bis(3-amino­pyridine)­nickel(II), [Ni(C10H9O2)2(C5H6N2)2], the NiII atom lies on a crystallographic center of symmetry. The coordination geometry around the NiII atom is distorted octahedral. Four O atoms of two 1-phenyl-1,3-butanedionate ligands form the equatorial plane, with Ni—O distances in the range 2.0160 (14)–2.0338 (14) A. The axial positions are occupied by N atoms of two 3-amino­pyridine ligands. The adduct mol­ecules translated by one unit along the a axis are linked by N—H⋯O hydrogen bonds, forming chains.
