ReCo2As crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ReCo2As cluster. Re(1) is bonded in a distorted bent 150 degrees geometry to one Co(2) and one As(1) atom. The Re(1)-Co(2) bond length is 0.62 Å. The Re(1)-As(1) bond length is 0.37 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to one Co(2) atom. The Co(1)-Co(2) bond length is 0.97 Å. In the second Co site, Co(2) is bonded in a distorted bent 150 degrees geometry to one Re(1) and one Co(1) atom. As(1) is bonded in a single-bond geometry to one Re(1) atom.
