The mol­ecular structure of the title compound, [Ni(C19H21N2P)2]I2·2CH3CN, shows two six-membered N-heterocyclic carbene/phosphane chelate rings that form a nearly square-planar coordination geometry around the NiII atom, which lies 0.190 (1) Å above the C2P2 plane. The sum of the bond angles at the NiII atom is 358.68 (6)°, with C-Ni-P bite angles of 82.89 (5) and 84.08 (6)°. The two carbene rings make a dihedral angle of 52.65 (8)°.

The mol­ecular structure of the title compound, [Cu(C11H16N3O3S)2], shows the CuII atom with a distorted square-planar coordination geometry from the N2O2 donor set of the two chelating 2-{[bis­(dimethyl­amino)­methyl­idene]amino}­benzene­sulfonate ligands. The CuII atom lies 0.065 (1) Å above the N2O2 plane and the Cu—O [2 × 1.945 (2) Å] and Cu—N bond lengths [1.968 (3) and 1.962 (3) Å] lie in expected ranges. The two aromatic ring planes make a dihedral angle of 85.48 (1)°.

In the title compound, [Fe(C11H20N2)2(CO)3], the Fe atom shows a distorted trigonal–bipyramidal geometry with three carbonyl and two carbene ligands. The latter have a cis arrangement, with a C—Fe—C angle of 90.60 (7)°. The Fe atom lies 0.007 (1) Å above the basal plane defined by two carbonyl and one carbene C atoms. The mol­ecular structure is closely related to that of the isomolecular but not isotypic Ru complex with an identical cis arrangement, so, in general, bond geometries lie in expected ranges. In the crystal, C—H...O hydrogen bonds link the mol­ecules into infinite zigzag chains extending along [010].
