Poly[[aqua[μ5-5-(isonicotinamido)isophthalato][μ4-5-(isonicotinamido)isophthalato]holmium(III)silver(I)] dihydrate]
The title heteronuclear complex, {[AgHo(C(14)H(8)N(2)O(5))(2)(H(2)O)]·2H(2)O}(n), has a three-dimensional polymeric structure, generated by the carboxyl-ate and pyridine groups of the 5-(isonicotinamido)-isophthalate (INAIP) ligands bridging the metal atoms. The Ho(III) atom is coordinated by seven O atoms from INAIP ligands and a water mol-ecule in a distorted square-anti-prismatic geometry, w...
متن کاملPoly[[μ2-acetato-aquadi-μ3-isonicotinato-holmium(III)silver(I)] perchlorate]
In the title three-dimensional heterometallic complex, {[AgHo(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the Ho(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of a water mol-ecule. The two-coordinate Ag(I) ion is bonded to two N atoms from two different isonicotinate anions. These m...
متن کاملHolmium Oxide Glass Wavelength Standards
Holmium oxide glass has been used as a wavelength standard for over four decades. These standards have shown insignificant spectral variation from batch to batch and from one manufacturer to another. The National Institute of Standards and Technology (NIST) has certified and recertified holmium oxide glass samples for over four decades. Over this period of time there has been no recorded instan...
متن کاملSilver : an Extensible Attribute Grammar System 1
Attribute grammar specification languages, like many domain specific languages, offer significant advantages to their users, such as high-level declarative constructs and domain-specific analyses. Despite these advantages, attribute grammars are often not adopted to the degree that their proponents envision. One practical obstacle to their adoption is a perceived lack of the both domain-specifi...
