Abstract:	Quantum-chemical density-functional theory (DFT) calculations, using the local-density approximation (LDA), have been performed for hydrogen-bounded silicon clusters to determine the electron density distribution of the Si-Si bond. The density distribution in the bonding region is compared with calculated and X-ray values of the bond in the crystal and found to be in good agreement. Using Hirshfeld's method for charge partitioning, a central Si atom was isolated and used for building a crystal. The corresponding structure factors agree very well (R < 0.14%) with experimental ones obtained by the Pendellosung method.
