Cr4B crystallizes in the orthorhombic F222 space group. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted bent 150 degrees geometry to two equivalent B(1) atoms. In the second Cr site, Cr(2) is bonded in a distorted bent 150 degrees geometry to two equivalent B(1) atoms. In the third Cr site, Cr(3) is bonded in a distorted water-like geometry to two equivalent B(1) atoms. In the fourth Cr site, Cr(4) is bonded in a 2-coordinate geometry to two equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to two equivalent Cr(1), two equivalent Cr(2), two equivalent Cr(3), and two equivalent Cr(4) atoms.
Cr4B crystallizes in the orthorhombic F222 space group. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted bent 150 degrees geometry to two equivalent B(1) atoms. Both Cr(1)-B(1) bond lengths are 2.14 Å. In the second Cr site, Cr(2) is bonded in a distorted bent 150 degrees geometry to two equivalent B(1) atoms. Both Cr(2)-B(1) bond lengths are 2.18 Å. In the third Cr site, Cr(3) is bonded in a distorted water-like geometry to two equivalent B(1) atoms. Both Cr(3)-B(1) bond lengths are 2.17 Å. In the fourth Cr site, Cr(4) is bonded in a 2-coordinate geometry to two equivalent B(1) atoms. Both Cr(4)-B(1) bond lengths are 2.17 Å.
