Abstract:
In the asymmetric unit of the title compound, [Mn(C(2)O(4))(C(3)H(10)N(2))(2)]Cl·H(2)O, there are two independent Mn(III) complexes, two Cl(-) anions and two uncoordinated water mol-ecules. Each Mn(III) atom is hexa-coordinated by four N atoms from two propane-1,3-diamine ligands and two O atoms from one oxalate ligand, resulting in a slightly distorted octa-hedral MnO(2)N(4) geometry. Mn-O and Mn-N bond lengths are in the ranges 1.969 (2)-2.020 (3) and 2.068 (3)-2.113 (4) Å, respectively. There are weak inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯O and N-H⋯Cl hydrogen bonds with D⋯A distances in the range 2.831 (4)-3.423 (3) Å.

Conformations of Ethane and Propane
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered...
π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
