SrCu2O3 crystallizes in the orthorhombic Pmmn space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Cu(1) atoms. In the second O site, O(1) is bonded to two equivalent Sr(1) and three equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OSr2Cu3 trigonal bipyramids.
SrCu2O3 crystallizes in the orthorhombic Pmmn space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Sr(1)-O(2) bond lengths are 2.44 Å. There are two shorter (2.53 Å) and two longer (2.79 Å) Sr(1)-O(1) bond lengths. Cu(1) is bonded in a square co-planar geometry to one O(2) and three equivalent O(1) atoms. The Cu(1)-O(2) bond length is 1.90 Å. There is one shorter (1.90 Å) and two longer (2.04 Å) Cu(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Cu(1) atoms. In the second O site, O(1) is bonded to two equivalent Sr(1) and three equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OSr2Cu3 trigonal bipyramids.
