The need for Phasor Measurement Units (PMUs) is rising as renewable energy sources become more prevalent in power networks since the rate of change frequency being deteriorated. Appropriate and accurate network measurements are a requirement precise monitoring control system. This paper presents low-cost PMU development, so-called PhasorsCatcher, networks, using sufficient but straightforward m...

The title compound, [SnCl4(H2O)2]·6H2O, was crystallized according to the solid-liquid phase diagram at lower temperatures. It is built-up of SnCl4(H2O)2 octa-hedral units (point group symmetry 2) and lattice water mol-ecules. An intricate three-dimensional network of O-H⋯O and O-H⋯Cl hydrogen bonds between the complex molecules and the lattice water molecules is formed in the crystal structure.

In the title mol-ecule, C(24)H(26)N(2)O(2), the two indol-2-one units, which are connected by a C=C double bond, are almost coplanar with an inter-planar angle of 6.8 (1)°. On cooling from 293 to 120 K, the space group changes from P2(1)/n to P2(1). Two intra-molecular C-H⋯O hydrogen bonds occur.

The title compound, octaaqua-(hydrogenfluorido)dicopper(II) hexa-fluoridoferrate(III) dihydrate, was synthesized under hydro-thermal conditions. The Cu atom is coordinated by one F and five O atoms within a highly distorted octa-hedron, forming dimeric [Cu(2)(H(2)O)(8)HF(2)](3+) units by edge sharing. These units are hydrogen bonded to [FeF(6)](3-) anions and to an inter-stitial water mol-ecule...

In the title compound, {[Mg(C(8)H(6)FO(3))(2)(H(2)O)(2)]·0.4H(2)O}(n), slightly distorted octa-hedral MgO(6) complex units have crystallographic inversion symmetry, the coordination polyhedron comprising two trans-related water mol-ecules and four carboxyl O-atom donors, two of which are bridging. Within the two-dimensional complex polymer which is parallel to (100), coordinating water mol-ecul...

The title compound, [Sn(C(7)H(7))(2)Cl(2)], exists as a monomeric tetra-hedral mol-ecule. The Sn atom lies on a special position of site symmetry 2. Adjacent mol-ecules are linked into a linear chain running along the b axis of the monoclinic unit cell by Sn⋯Cl bridges of 3.7275 (4) Å.

There are two mol-ecules in the asymmetric unit of the title compound, C(8)H(4)ClNO(2). In the crystal, they are linked by N-H⋯O hydrogen bonds, generating centrosymmetric, tetra-meric assemblies. A C-H⋯O inter-action also occurs.

There are two mol-ecules in the asymmetric unit (Z' = 2) of the title compound, C(13)H(14)ClN(3), Each mol-ecule is linked by N-H⋯N hydrogen bonds to another of the same type in a chain in [110]. The crystal studied was a non-merohedral twin with components 0.622 (2) and 0.378 (2).
