Ta2CrSi6 is Titanium Disilicide-derived structured and crystallizes in the orthorhombic C222 space group. Ta(1) is bonded in a 10-coordinate geometry to two equivalent Si(1) and eight equivalent Si(2) atoms. Cr(1) is bonded in a 10-coordinate geometry to four equivalent Si(2) and six equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to two equivalent Ta(1), three equivalent Cr(1), two equivalent Si(2), and three equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent Ta(1), one Cr(1), one Si(1), and four equivalent Si(2) atoms.
Ta2CrSi6 is Titanium Disilicide-derived structured and crystallizes in the orthorhombic C222 space group. Ta(1) is bonded in a 10-coordinate geometry to two equivalent Si(1) and eight equivalent Si(2) atoms. Both Ta(1)-Si(1) bond lengths are 2.59 Å. There are a spread of Ta(1)-Si(2) bond distances ranging from 2.63-2.76 Å. Cr(1) is bonded in a 10-coordinate geometry to four equivalent Si(2) and six equivalent Si(1) atoms. All Cr(1)-Si(2) bond lengths are 2.51 Å. There are four shorter (2.68 Å) and two longer (2.82 Å) Cr(1)-Si(1) bond lengths. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to two equivalent Ta(1), three equivalent Cr(1), two equivalent Si(2), and three equivalent Si(1) atoms. Both Si(1)-Si(2) bond lengths are 2.50 Å. There is one shorter (2.64 Å) and two longer (2.78 Å) Si(1)-Si(1) bond lengths. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent Ta(1), one Cr(1), one Si(1), and four equivalent Si(2) atoms. There are a spread of Si(2)-Si(2) bond distances ranging from 2.61-2.87 Å.
