Abstract

Solid-state reaction of Ca, CaCl2, Sr, SrCl2, C and BN at 900°C for 3 days yielded transparent red needles of Ca2.57(4)Sr0.43(4)Cl2[CBN] as minority product (<10%) mixed with crystals of isotypic yellow Ca3Cl2[CBN] and orange Sr3Cl2[CBN]. Ca2.57(4)Sr0.43(4)Cl2[CBN] crystallizes in the space group Pnma (no.62) with the unit cell parameters of a=1389.2(6), b=386.05(15) and c=1131.2(4)pm (Z=4). The Raman spectrum confirms the presence of the [CBN]4− unit. The incremental volume of the [CBN]4− is calculated to be 50.7(10)Å3.

Keywords: [CBN]4− anion; calcium; crystal structure; fractional volume; Raman spectrum; strontium
