Bottom Line: In the title compound, [Rh(C6H5N4)Cl2(C12H27P)2], the Rh(III) ion is chelated by the singly deprotonated 2,2'-biimidazolate (Hbim(-)) ligand and coordinated by two chloride ions and two tri-n-butyl-phosphane ligands.The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere.The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N-H⋯N hydrogen bonds.

ABSTRACT
In the title compound, [Rh(C6H5N4)Cl2(C12H27P)2], the Rh(III) ion is chelated by the singly deprotonated 2,2'-biimidazolate (Hbim(-)) ligand and coordinated by two chloride ions and two tri-n-butyl-phosphane ligands. The chloride ions and N atoms of the Hbim(-) ligand lie in a plane where the sum of X-Rh-X angles between cis sites is 360°. The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere. The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N-H⋯N hydrogen bonds.

Mentions: In the structure of (I), the RhIII ion is chelated by the singly deprotonated biimidazolate (Hbim−) ligand and coordinated by two chloride ions and two tri-n-butyl­phosphane ligands (Fig. 1 ▶). The chloride ions and N atoms of the Hbim− ligand lie in a plane where the sum of X—Rh—X angles between cis-sites is 360°. The small bite angle of N1—Rh1—N3 [78.98 (7)°] makes the other angles wider than 90° [N1—Rh1—Cl1 93.28 (5), N3—Rh1—Cl2 94.18 (5) and Cl1—Rh1—Cl2 93.56 (2)°]. The phosphane ligands occupy the axial sites with a P1—Rh1—P2 angle of 176.29 (2)°.
