Ca 9 Cl 8 (BC 2 ) 2 was obtained by solid state reaction of a mixture of CaCl 2 , Ca, B and C. The structure was solved by single crystal X‐ray structure determination. Ca 9 Cl 8 (BC 2 ) 2 crystallizes in the orthorhombic space group Cmcm (No. 63, a = 1162.91(8) pm, b = 1341.59(10) pm and c = 1208.62(9) pm, Z = 4). The most striking element of the title compound is the bent BC 2 5– unit that is surrounded by a bicapped trigonal prismatic arrangement of calcium ions.
